Batch image generation and manipulation tool supporting Stable Diffusion and related techniques / algorithms, with support for video and animated image processing.

Project description

Overview

Documentation Status

dgenerate is a command line tool and library for generating images and animation sequences using Stable Diffusion and related techniques / models.

You can use dgenerate to generate multiple images or animated outputs using multiple combinations of diffusion input parameters in batch, so that the differences in generated output can be compared / curated easily.

Simple txt2img generation without image inputs is supported, as well as img2img and inpainting, and ControlNets.

Animated output can be produced by processing every frame of a Video, GIF, WebP, or APNG through various implementations of diffusion in img2img or inpainting mode, as well as with ControlNets and control guidance images, in any combination thereof. MP4 (h264) video can be written without memory constraints related to frame count. GIF, WebP, and PNG/APNG can be written WITH memory constraints, IE: all frames exist in memory at once before being written.

Video input of any runtime can be processed without memory constraints related to the video size. Many video formats are supported through the use of PyAV (ffmpeg).

Animated image input such as GIF, APNG (extension must be .apng), and WebP, can also be processed WITH memory constraints, IE: all frames exist in memory at once after an animated image is read.

PNG, JPEG, JPEG-2000, TGA (Targa), BMP, and PSD (Photoshop) are supported for static image inputs.

In addition to diffusion, dgenerate also supports the processing of any supported image, video, or animated image using any of its built in image processors, which include various edge detectors, depth detectors, segment generation, normal map generation, pose detection, non-diffusion based AI upscaling, and more.

This software requires an Nvidia GPU supporting CUDA 12.1+, CPU rendering is possible for some operations but extraordinarily slow.

                 model_path

Batch image generation and manipulation tool supporting Stable Diffusion and related techniques /
algorithms, with support for video and animated image processing.

positional arguments:
  model_path            huggingface model repository slug, huggingface blob link to a model file, path
                        to folder on disk, or path to a .pt, .pth, .bin, .ckpt, or .safetensors file.

options:
  -h, --help            show this help message and exit
  -v, --verbose         Output information useful for debugging, such as pipeline call and model load
                        parameters.
  --version             Show dgenerate's version and exit
  --plugin-modules PATH [PATH ...]
                        Specify one or more plugin module folder paths (folder containing __init__.py)
                        or python .py file paths to load as plugins. Plugin modules can currently
                        implement image processors and config directives.
  --sub-command SUB_COMMAND
                        Specify the name a sub-command to invoke. dgenerate exposes some extra image
                        processing functionality through the use of sub-commands. Sub commands
                        essentially replace the entire set of accepted arguments with those of a sub-
                        command which implements additional functionality. See --sub-command-help for a
                        list of sub-commands and help.
  --sub-command-help [SUB_COMMAND ...]
                        List available sub-commands, providing sub-command names will produce their
                        documentation. Calling a subcommand with "--sub-command name --help" will
                        produce argument help output for that subcommand.
  -ofm, --offline-mode  Whether dgenerate should try to download huggingface models that do not exist in
                        the disk cache, or only use what is available in the cache. Referencing a model
                        on huggingface that has not been cached because it was not previously downloaded
                        will result in a failure when using this option.
  --templates-help [VARIABLE_NAME ...]
                        Print a list of template variables available in dgenerate configs during batch
                        processing from STDIN. When used as a command option, their values are not
                        presented, just their names and types. Specifying names will print type
                        information for those variable names.
  --directives-help [DIRECTIVE_NAME ...]
                        Print a list of directives available in dgenerate configs during batch
                        processing from STDIN. Providing names will print documentation for the
                        specified directive names. When used with --plugin-modules, directives
                        implemented by the specified plugins will also be listed.
  -mt MODEL_TYPE, --model-type MODEL_TYPE
                        Use when loading different model types. Currently supported: torch, torch-
                        pix2pix, torch-sdxl, torch-sdxl-pix2pix, torch-upscaler-x2, torch-upscaler-x4,
                        torch-if, torch-ifs, torch-ifs-img2img, or torch-s-cascade. (default: torch)
  -rev BRANCH, --revision BRANCH
                        The model revision to use when loading from a huggingface repository, (The git
                        branch / tag, default is "main")
  -var VARIANT, --variant VARIANT
                        If specified when loading from a huggingface repository or folder, load weights
                        from "variant" filename, e.g. "pytorch_model.<variant>.safetensors". Defaults to
                        automatic selection. This option is ignored if using flax.
  -sbf SUBFOLDER, --subfolder SUBFOLDER
                        Main model subfolder. If specified when loading from a huggingface repository or
                        folder, load weights from the specified subfolder.
  -atk TOKEN, --auth-token TOKEN
                        Huggingface auth token. Required to download restricted repositories that have
                        access permissions granted to your huggingface account.
  -bs INTEGER, --batch-size INTEGER
                        The number of image variations to produce per set of individual diffusion
                        parameters in one rendering step simultaneously on a single GPU. When using
                        flax, batch size is controlled by the environmental variable
                        CUDA_VISIBLE_DEVICES which is a comma separated list of GPU device numbers (as
                        listed by nvidia-smi). Usage of this argument with --model-type flax* will cause
                        an error, diffusion with flax will generate an image on every GPU that is
                        visible to CUDA and this is currently unchangeable. When generating animations
                        with a --batch-size greater than one, a separate animation (with the filename
                        suffix "animation_N") will be written to for each image in the batch. If
                        --batch-grid-size is specified when producing an animation then the image grid
                        is used for the output frames. During animation rendering each image in the
                        batch will still be written to the output directory along side the produced
                        animation as either suffixed files or image grids depending on the options you
                        choose. (Torch Default: 1)
  -bgs SIZE, --batch-grid-size SIZE
                        Produce a single image containing a grid of images with the number of
                        COLUMNSxROWS given to this argument when --batch-size is greater than 1, or when
                        using flax with multiple GPUs visible (via the environmental variable
                        CUDA_VISIBLE_DEVICES). If not specified with a --batch-size greater than 1,
                        images will be written individually with an image number suffix (image_N) in the
                        filename signifying which image in the batch they are.
  -un UNET_URI, --unet UNET_URI
                        Specify a UNet using a URI. Examples: "huggingface/unet",
                        "huggingface/unet;revision=main", "unet_folder_on_disk". Blob links / single
                        file loads are not supported for UNets. The "revision" argument specifies the
                        model revision to use for the UNet when loading from huggingface repository or
                        blob link, (The git branch / tag, default is "main"). The "variant" argument
                        specifies the UNet model variant, it is only supported for torch type models it
                        is not supported for flax. If "variant" is specified when loading from a
                        huggingface repository or folder, weights will be loaded from "variant"
                        filename, e.g. "pytorch_model.<variant>.safetensors. "variant" defaults to the
                        value of --variant if it is not specified in the URI. The "subfolder" argument
                        specifies the UNet model subfolder, if specified when loading from a huggingface
                        repository or folder, weights from the specified subfolder. The "dtype" argument
                        specifies the UNet model precision, it defaults to the value of -t/--dtype and
                        should be one of: auto, bfloat16, float16, or float32. If you wish to load
                        weights directly from a path on disk, you must point this argument at the folder
                        they exist in, which should also contain the config.json file for the UNet. For
                        example, a downloaded repository folder from huggingface.
  -un2 UNET_URI, --unet2 UNET_URI
                        Specify a second UNet, this is only valid when using SDXL or Stable Cascade
                        model types. This UNet will be used for the SDXL refiner, or Stable Cascade
                        decoder model.
  -vae VAE_URI, --vae VAE_URI
                        Specify a VAE using a URI. When using torch models the URI syntax is:
                        "AutoEncoderClass;model=(huggingface repository slug/blob link or file/folder
                        path)". Examples: "AutoencoderKL;model=vae.pt",
                        "AsymmetricAutoencoderKL;model=huggingface/vae",
                        "AutoencoderTiny;model=huggingface/vae",
                        "ConsistencyDecoderVAE;model=huggingface/vae". When using a Flax model, there is
                        currently only one available encoder class:
                        "FlaxAutoencoderKL;model=huggingface/vae". The AutoencoderKL encoder class
                        accepts huggingface repository slugs/blob links, .pt, .pth, .bin, .ckpt, and
                        .safetensors files. Other encoders can only accept huggingface repository
                        slugs/blob links, or a path to a folder on disk with the model configuration and
                        model file(s). Aside from the "model" argument, there are four other optional
                        arguments that can be specified, these include "revision", "variant",
                        "subfolder", "dtype". They can be specified as so in any order, they are not
                        positional: "AutoencoderKL;model=huggingface/vae;revision=main;variant=fp16;subf
                        older=sub_folder;dtype=float16". The "revision" argument specifies the model
                        revision to use for the VAE when loading from huggingface repository or blob
                        link, (The git branch / tag, default is "main"). The "variant" argument
                        specifies the VAE model variant, it is only supported for torch type models it
                        is not supported for flax. If "variant" is specified when loading from a
                        huggingface repository or folder, weights will be loaded from "variant"
                        filename, e.g. "pytorch_model.<variant>.safetensors. "variant" in the case of
                        --vae does not default to the value of --variant to prevent failures during
                        common use cases. The "subfolder" argument specifies the VAE model subfolder, if
                        specified when loading from a huggingface repository or folder, weights from the
                        specified subfolder. The "dtype" argument specifies the VAE model precision, it
                        defaults to the value of -t/--dtype and should be one of: auto, bfloat16,
                        float16, or float32. If you wish to load a weights file directly from disk, the
                        simplest way is: --vae "AutoencoderKL;my_vae.safetensors", or with a dtype
                        "AutoencoderKL;my_vae.safetensors;dtype=float16". All loading arguments except
                        "dtype" are unused in this case and may produce an error message if used. If you
                        wish to load a specific weight file from a huggingface repository, use the blob
                        link loading syntax: --vae
                        "AutoencoderKL;https://huggingface.co/UserName/repository-
                        name/blob/main/vae_model.safetensors", the "revision" argument may be used with
                        this syntax.
  -vt, --vae-tiling     Enable VAE tiling (torch Stable Diffusion only). Assists in the generation of
                        large images with lower memory overhead. The VAE will split the input tensor
                        into tiles to compute decoding and encoding in several steps. This is useful for
                        saving a large amount of memory and to allow processing larger images. Note that
                        if you are using --control-nets you may still run into memory issues generating
                        large images, or with --batch-size greater than 1.
  -vs, --vae-slicing    Enable VAE slicing (torch Stable Diffusion models only). Assists in the
                        generation of large images with lower memory overhead. The VAE will split the
                        input tensor in slices to compute decoding in several steps. This is useful to
                        save some memory, especially when --batch-size is greater than 1. Note that if
                        you are using --control-nets you may still run into memory issues generating
                        large images.
  -lra LORA_URI [LORA_URI ...], --loras LORA_URI [LORA_URI ...]
                        Specify one or more LoRA models using URIs (flax not supported). These should be
                        a huggingface repository slug, path to model file on disk (for example, a .pt,
                        .pth, .bin, .ckpt, or .safetensors file), or model folder containing model
                        files. huggingface blob links are not supported, see "subfolder" and "weight-
                        name" below instead. Optional arguments can be provided after a LoRA model
                        specification, these include: "scale", "revision", "subfolder", and "weight-
                        name". They can be specified as so in any order, they are not positional:
                        "huggingface/lora;scale=1.0;revision=main;subfolder=repo_subfolder;weight-
                        name=lora.safetensors". The "scale" argument indicates the scale factor of the
                        LoRA. The "revision" argument specifies the model revision to use for the LoRA
                        when loading from huggingface repository, (The git branch / tag, default is
                        "main"). The "subfolder" argument specifies the LoRA model subfolder, if
                        specified when loading from a huggingface repository or folder, weights from the
                        specified subfolder. The "weight-name" argument indicates the name of the
                        weights file to be loaded when loading from a huggingface repository or folder
                        on disk. If you wish to load a weights file directly from disk, the simplest way
                        is: --loras "my_lora.safetensors", or with a scale
                        "my_lora.safetensors;scale=1.0", all other loading arguments are unused in this
                        case and may produce an error message if used.
  -ti URI [URI ...], --textual-inversions URI [URI ...]
                        Specify one or more Textual Inversion models using URIs (flax and SDXL not
                        supported). These should be a huggingface repository slug, path to model file on
                        disk (for example, a .pt, .pth, .bin, .ckpt, or .safetensors file), or model
                        folder containing model files. huggingface blob links are not supported, see
                        "subfolder" and "weight-name" below instead. Optional arguments can be provided
                        after the Textual Inversion model specification, these include: "revision",
                        "subfolder", and "weight-name". They can be specified as so in any order, they
                        are not positional:
                        "huggingface/ti_model;revision=main;subfolder=repo_subfolder;weight-
                        name=lora.safetensors". The "revision" argument specifies the model revision to
                        use for the Textual Inversion model when loading from huggingface repository,
                        (The git branch / tag, default is "main"). The "subfolder" argument specifies
                        the Textual Inversion model subfolder, if specified when loading from a
                        huggingface repository or folder, weights from the specified subfolder. The
                        "weight-name" argument indicates the name of the weights file to be loaded when
                        loading from a huggingface repository or folder on disk. If you wish to load a
                        weights file directly from disk, the simplest way is: --textual-inversions
                        "my_ti_model.safetensors", all other loading arguments are unused in this case
                        and may produce an error message if used.
  -cn CONTROL_NET_URI [CONTROL_NET_URI ...], --control-nets CONTROL_NET_URI [CONTROL_NET_URI ...]
                        Specify one or more ControlNet models using URIs. This should be a huggingface
                        repository slug / blob link, path to model file on disk (for example, a .pt,
                        .pth, .bin, .ckpt, or .safetensors file), or model folder containing model
                        files. Optional arguments can be provided after the ControlNet model
                        specification, for torch these include: "scale", "start", "end", "revision",
                        "variant", "subfolder", and "dtype". For flax: "scale", "revision", "subfolder",
                        "dtype", "from_torch" (bool) They can be specified as so in any order, they are
                        not positional: "huggingface/controlnet;scale=1.0;start=0.0;end=1.0;revision=mai
                        n;variant=fp16;subfolder=repo_subfolder;dtype=float16". The "scale" argument
                        specifies the scaling factor applied to the ControlNet model, the default value
                        is 1.0. The "start" (only for --model-type "torch*") argument specifies at what
                        fraction of the total inference steps to begin applying the ControlNet, defaults
                        to 0.0, IE: the very beginning. The "end" (only for --model-type "torch*")
                        argument specifies at what fraction of the total inference steps to stop
                        applying the ControlNet, defaults to 1.0, IE: the very end. The "revision"
                        argument specifies the model revision to use for the ControlNet model when
                        loading from huggingface repository, (The git branch / tag, default is "main").
                        The "variant" (only for --model-type "torch*") argument specifies the ControlNet
                        model variant, if "variant" is specified when loading from a huggingface
                        repository or folder, weights will be loaded from "variant" filename, e.g.
                        "pytorch_model.<variant>.safetensors. "variant" defaults to automatic selection
                        and is ignored if using flax. "variant" in the case of --control-nets does not
                        default to the value of --variant to prevent failures during common use cases.
                        The "subfolder" argument specifies the ControlNet model subfolder, if specified
                        when loading from a huggingface repository or folder, weights from the specified
                        subfolder. The "dtype" argument specifies the ControlNet model precision, it
                        defaults to the value of -t/--dtype and should be one of: auto, bfloat16,
                        float16, or float32. The "from_torch" (only for --model-type flax) this argument
                        specifies that the ControlNet is to be loaded and converted from a huggingface
                        repository or file that is designed for pytorch. (Defaults to false) If you wish
                        to load a weights file directly from disk, the simplest way is: --control-nets
                        "my_controlnet.safetensors" or --control-nets
                        "my_controlnet.safetensors;scale=1.0;dtype=float16", all other loading arguments
                        aside from "scale" and "dtype" are unused in this case and may produce an error
                        message if used ("from_torch" is available when using flax). If you wish to load
                        a specific weight file from a huggingface repository, use the blob link loading
                        syntax: --control-nets "https://huggingface.co/UserName/repository-
                        name/blob/main/controlnet.safetensors", the "revision" argument may be used with
                        this syntax.
  -sch SCHEDULER_NAME, --scheduler SCHEDULER_NAME
                        Specify a scheduler (sampler) by name. Passing "help" to this argument will
                        print the compatible schedulers for a model without generating any images. Torch
                        schedulers: (DDIMScheduler, DDPMScheduler, PNDMScheduler, LMSDiscreteScheduler,
                        EulerDiscreteScheduler, HeunDiscreteScheduler, EulerAncestralDiscreteScheduler,
                        DPMSolverMultistepScheduler, DPMSolverSinglestepScheduler,
                        KDPM2DiscreteScheduler, KDPM2AncestralDiscreteScheduler, DEISMultistepScheduler,
                        UniPCMultistepScheduler, DPMSolverSDEScheduler, EDMEulerScheduler).
  -mqo, --model-sequential-offload
                        Force sequential model offloading for the main pipeline, this may drastically
                        reduce memory consumption and allow large models to run when they would
                        otherwise not fit in your GPUs VRAM. Inference will be much slower. Mutually
                        exclusive with --model-cpu-offload
  -mco, --model-cpu-offload
                        Force model cpu offloading for the main pipeline, this may reduce memory
                        consumption and allow large models to run when they would otherwise not fit in
                        your GPUs VRAM. Inference will be slower. Mutually exclusive with --model-

  --s-cascade-decoder MODEL_URI
                        Specify a Stable Cascade (torch-s-cascade) decoder model path using a URI. This
                        should be a huggingface repository slug / blob link, path to model file on disk
                        (for example, a .pt, .pth, .bin, .ckpt, or .safetensors file), or model folder
                        containing model files. Optional arguments can be provided after the decoder
                        model specification, these include: "revision", "variant", "subfolder", and
                        "dtype". They can be specified as so in any order, they are not positional: "hug
                        gingface/decoder_model;revision=main;variant=fp16;subfolder=repo_subfolder;dtype
                        =float16". The "revision" argument specifies the model revision to use for the

                        branch / tag, default is "main"). The "variant" argument specifies the decoder
                        model variant and defaults to the value of --variant. When "variant" is
                        specified when loading from a huggingface repository or folder, weights will be
                        loaded from "variant" filename, e.g. "pytorch_model.<variant>.safetensors. The
                        "subfolder" argument specifies the decoder model subfolder, if specified when
                        loading from a huggingface repository or folder, weights from the specified
                        subfolder. The "dtype" argument specifies the Stable Cascade decoder model
                        precision, it defaults to the value of -t/--dtype and should be one of: auto,
                        bfloat16, float16, or float32. If you wish to load a weights file directly from
                        disk, the simplest way is: --sdxl-refiner "my_decoder.safetensors" or --sdxl-
                        refiner "my_decoder.safetensors;dtype=float16", all other loading arguments

                        used. If you wish to load a specific weight file from a huggingface repository,
                        use the blob link loading syntax: --s-cascade-decoder
                        "https://huggingface.co/UserName/repository-name/blob/main/decoder.safetensors",
                        the "revision" argument may be used with this syntax.
  -dqo, --s-cascade-decoder-sequential-offload
                        Force sequential model offloading for the Stable Cascade decoder pipeline, this
                        may drastically reduce memory consumption and allow large models to run when

  --s-cascade-decoder-prompts PROMPT [PROMPT ...]
                        One or more prompts to try with the Stable Cascade decoder model, by default the
                        decoder model gets the primary prompt, this argument overrides that with a
                        prompt of your choosing. The negative prompt component can be specified with the
                        same syntax as --prompts
  --s-cascade-decoder-inference-steps INTEGER [INTEGER ...]

  --sdxl-refiner-scheduler SCHEDULER_NAME
                        Specify a scheduler (sampler) by name for the SDXL refiner pass. Operates the
                        exact same way as --scheduler including the "help" option. Defaults to the value
                        of --scheduler.
  --sdxl-refiner-edit   Force the SDXL refiner to operate in edit mode instead of cooperative denoising
                        mode as it would normally do for inpainting and ControlNet usage. The main model
                        will preform the full amount of inference steps requested by --inference-steps.
                        The output of the main model will be passed to the refiner model and processed
                        with an image seed strength in img2img mode determined by (1.0 - high-noise-
                        fraction)
  --sdxl-second-prompts PROMPT [PROMPT ...]

                        default the model is passed the primary prompt for this value, this option
                        allows you to choose a different prompt. The negative prompt component can be
                        specified with the same syntax as --prompts

                        can be used to generate an image that appears to be "cropped" from the position
                        --sdxl-crops-coords-top-left downwards. Favorable, well-centered images are
                        usually achieved by setting --sdxl-crops-coords-top-left to "0,0". Part of
                        SDXL's micro-conditioning as explained in section 2.2 of

                        parameters in the format (WIDTH)x(HEIGHT). For most cases, --sdxl-target-size
                        should be set to the desired height and width of the generated image. If not
                        specified it will default to --output-size or the size of any input images. Part
                        of SDXL's micro-conditioning as explained in section 2.2 of

  --sdxl-refiner-prompts PROMPT [PROMPT ...]
                        One or more prompts to try with the SDXL refiner model, by default the refiner
                        model gets the primary prompt, this argument overrides that with a prompt of
                        your choosing. The negative prompt component can be specified with the same
                        syntax as --prompts
  --sdxl-refiner-clip-skips INTEGER [INTEGER ...]
                        One or more clip skip override values to try for the SDXL refiner, which
                        normally uses the clip skip value for the main model when it is defined by
                        --clip-skips.

                        One or more prompts to try with the SDXL refiner models secondary text encoder,
                        by default the refiner model gets the primary prompt passed to its second text
                        encoder, this argument overrides that with a prompt of your choosing. The
                        negative prompt component can be specified with the same syntax as --prompts

  -hnf FLOAT [FLOAT ...], --sdxl-high-noise-fractions FLOAT [FLOAT ...]
                        One or more high-noise-fraction values for Stable Diffusion XL (torch-sdxl),
                        this fraction of inference steps will be processed by the base model, while the
                        rest will be processed by the refiner model. Multiple values to this argument
                        will result in additional generation steps for each value. In certain situations
                        when the mixture of denoisers algorithm is not supported, such as when using
                        --control-nets and inpainting with SDXL, the inverse proportion of this value
                        IE: (1.0 - high-noise-fraction) becomes the --image-seed-strengths input to the
                        SDXL refiner. (default: [0.8])
  -ri INT [INT ...], --sdxl-refiner-inference-steps INT [INT ...]
                        One or more inference steps values for the SDXL refiner when in use. Override
                        the number of inference steps used by the SDXL refiner, which defaults to the
                        value taken from --inference-steps.
  -rg FLOAT [FLOAT ...], --sdxl-refiner-guidance-scales FLOAT [FLOAT ...]
                        One or more guidance scale values for the SDXL refiner when in use. Override the
                        guidance scale value used by the SDXL refiner, which defaults to the value taken
                        from --guidance-scales.
  -rgr FLOAT [FLOAT ...], --sdxl-refiner-guidance-rescales FLOAT [FLOAT ...]
                        One or more guidance rescale values for the SDXL refiner when in use. Override
                        the guidance rescale value used by the SDXL refiner, which defaults to the value
                        taken from --guidance-rescales.
  -sc, --safety-checker
                        Enable safety checker loading, this is off by default. When turned on images
                        with NSFW content detected may result in solid black output. Some pretrained
                        models have no safety checker model present, in that case this option has no
                        effect.
  -d DEVICE, --device DEVICE
                        cuda / cpu. (default: cuda). Use: cuda:0, cuda:1, cuda:2, etc. to specify a
                        specific GPU. This argument is ignored when using flax, for flax use the
                        environmental variable CUDA_VISIBLE_DEVICES to specify which GPUs are visible to
                        cuda, flax will use every visible GPU.
  -t DTYPE, --dtype DTYPE
                        Model precision: auto, bfloat16, float16, or float32. (default: auto)
  -s SIZE, --output-size SIZE
                        Image output size, for txt2img generation, this is the exact output size. The
                        dimensions specified for this value must be aligned by 8 or you will receive an
                        error message. If an --image-seeds URI is used its Seed, Mask, and/or Control
                        component image sources will be resized to this dimension with aspect ratio
                        maintained before being used for generation by default. Unless --no-aspect is
                        specified, width will be fixed and a new height (aligned by 8) will be
                        calculated for the input images. In most cases resizing the image inputs will
                        result in an image output of an equal size to the inputs, except in the case of
                        upscalers and Deep Floyd --model-type values (torch-if*). If only one integer
                        value is provided, that is the value for both dimensions. X/Y dimension values
                        should be separated by "x". This value defaults to 512x512 for Stable Diffusion
                        when no --image-seeds are specified (IE txt2img mode), 1024x1024 for Stable
                        Diffusion XL (SDXL) model types, and 64x64 for --model-type torch-if (Deep Floyd
                        stage 1). Deep Floyd stage 1 images passed to superscaler models (--model-type
                        torch-ifs*) that are specified with the 'floyd' keyword argument in an --image-
                        seeds definition are never resized or processed in any way.
  -na, --no-aspect      This option disables aspect correct resizing of images provided to --image-seeds
                        globally. Seed, Mask, and Control guidance images will be resized to the closest
                        dimension specified by --output-size that is aligned by 8 pixels with no
                        consideration of the source aspect ratio. This can be overriden at the --image-
                        seeds level with the image seed keyword argument 'aspect=true/false'.
  -o PATH, --output-path PATH
                        Output path for generated images and files. This directory will be created if it
                        does not exist. (default: ./output)
  -op PREFIX, --output-prefix PREFIX
                        Name prefix for generated images and files. This prefix will be added to the
                        beginning of every generated file, followed by an underscore.
  -ox, --output-overwrite
                        Enable overwrites of files in the output directory that already exists. The
                        default behavior is not to do this, and instead append a filename suffix:
                        "_duplicate_(number)" when it is detected that the generated file name already
                        exists.
  -oc, --output-configs
                        Write a configuration text file for every output image or animation. The text
                        file can be used reproduce that particular output image or animation by piping
                        it to dgenerate STDIN, for example "dgenerate < config.txt". These files will be
                        written to --output-directory and are affected by --output-prefix and --output-
                        overwrite as well. The files will be named after their corresponding image or
                        animation file. Configuration files produced for animation frame images will
                        utilize --frame-start and --frame-end to specify the frame number.
  -om, --output-metadata
                        Write the information produced by --output-configs to the PNG metadata of each
                        image. Metadata will not be written to animated files (yet). The data is written
                        to a PNG metadata property named DgenerateConfig and can be read using
                        ImageMagick like so: "magick identify -format "%[Property:DgenerateConfig]
                        generated_file.png".
  -p PROMPT [PROMPT ...], --prompts PROMPT [PROMPT ...]
                        One or more prompts to try, an image group is generated for each prompt, prompt
                        data is split by ; (semi-colon). The first value is the positive text influence,
                        things you want to see. The Second value is negative influence IE. things you
                        don't want to see. Example: --prompts "shrek flying a tesla over detroit;
                        clouds, rain, missiles". (default: [(empty string)])
  -cs INTEGER [INTEGER ...], --clip-skips INTEGER [INTEGER ...]
                        One or more clip skip values to try. Clip skip is the number of layers to be
                        skipped from CLIP while computing the prompt embeddings, it must be a value
                        greater than or equal to zero. A value of 1 means that the output of the pre-
                        final layer will be used for computing the prompt embeddings. This is only
                        supported for --model-type values "torch" and "torch-sdxl", including with
                        --control-nets.
  -se SEED [SEED ...], --seeds SEED [SEED ...]
                        One or more seeds to try, define fixed seeds to achieve deterministic output.
                        This argument may not be used when --gse/--gen-seeds is used. (default:
                        [randint(0, 99999999999999)])
  -sei, --seeds-to-images
                        When this option is enabled, each provided --seeds value or value generated by
                        --gen-seeds is used for the corresponding image input given by --image-seeds. If
                        the amount of --seeds given is not identical to that of the amount of --image-
                        seeds given, the seed is determined as: seed = seeds[image_seed_index %
                        len(seeds)], IE: it wraps around.
  -gse COUNT, --gen-seeds COUNT
                        Auto generate N random seeds to try. This argument may not be used when
                        -se/--seeds is used.
  -af FORMAT, --animation-format FORMAT
                        Output format when generating an animation from an input video / gif / webp etc.
                        Value must be one of: mp4, png, apng, gif, or webp. You may also specify
                        "frames" to indicate that only frames should be output and no coalesced
                        animation file should be rendered. (default: mp4)
  -if FORMAT, --image-format FORMAT
                        Output format when writing static images. Any selection other than "png" is not
                        compatible with --output-metadata. Value must be one of: png, apng, blp, bmp,
                        dib, bufr, pcx, dds, ps, eps, gif, grib, h5, hdf, jp2, j2k, jpc, jpf, jpx, j2c,
                        icns, ico, im, jfif, jpe, jpg, jpeg, tif, tiff, mpo, msp, palm, pdf, pbm, pgm,
                        ppm, pnm, pfm, bw, rgb, rgba, sgi, tga, icb, vda, vst, webp, wmf, emf, or xbm.
                        (default: png)
  -nf, --no-frames      Do not write frame images individually when rendering an animation, only write
                        the animation file. This option is incompatible with --animation-format frames.
  -fs FRAME_NUMBER, --frame-start FRAME_NUMBER
                        Starting frame slice point for animated files (zero-indexed), the specified
                        frame will be included. (default: 0)
  -fe FRAME_NUMBER, --frame-end FRAME_NUMBER
                        Ending frame slice point for animated files (zero-indexed), the specified frame
                        will be included.
  -is SEED [SEED ...], --image-seeds SEED [SEED ...]
                        One or more image seed URIs to process, these may consist of URLs or file paths.
                        Videos / GIFs / WEBP files will result in frames being rendered as well as an
                        animated output file being generated if more than one frame is available in the
                        input file. Inpainting for static images can be achieved by specifying a black
                        and white mask image in each image seed string using a semicolon as the
                        separating character, like so: "my-seed-image.png;my-image-mask.png", white
                        areas of the mask indicate where generated content is to be placed in your seed
                        image. Output dimensions specific to the image seed can be specified by placing
                        the dimension at the end of the string following a semicolon like so: "my-seed-
                        image.png;512x512" or "my-seed-image.png;my-image-mask.png;512x512". When using
                        --control-nets, a singular image specification is interpreted as the control
                        guidance image, and you can specify multiple control image sources by separating
                        them with commas in the case where multiple ControlNets are specified, IE:
                        (--image-seeds "control-image1.png, control-image2.png") OR (--image-seeds
                        "seed.png;control=control-image1.png, control-image2.png"). Using --control-nets
                        with img2img or inpainting can be accomplished with the syntax: "my-seed-
                        image.png;mask=my-image-mask.png;control=my-control-image.png;resize=512x512".
                        The "mask" and "resize" arguments are optional when using --control-nets.
                        Videos, GIFs, and WEBP are also supported as inputs when using --control-nets,
                        even for the "control" argument. --image-seeds is capable of reading from
                        multiple animated files at once or any combination of animated files and images,
                        the animated file with the least amount of frames dictates how many frames are
                        generated and static images are duplicated over the total amount of frames. The
                        keyword argument "aspect" can be used to determine resizing behavior when the
                        global argument --output-size or the local keyword argument "resize" is
                        specified, it is a boolean argument indicating whether aspect ratio of the input
                        image should be respected or ignored. The keyword argument "floyd" can be used
                        to specify images from a previous deep floyd stage when using --model-type
                        torch-ifs*. When keyword arguments are present, all applicable images such as
                        "mask", "control", etc. must also be defined with keyword arguments instead of
                        with the short syntax.
  -sip PROCESSOR_URI [PROCESSOR_URI ...], --seed-image-processors PROCESSOR_URI [PROCESSOR_URI ...]
                        Specify one or more image processor actions to preform on the primary image
                        specified by --image-seeds. For example: --seed-image-processors "flip" "mirror"
                        "grayscale". To obtain more information about what image processors are
                        available and how to use them, see: --image-processor-help.
  -mip PROCESSOR_URI [PROCESSOR_URI ...], --mask-image-processors PROCESSOR_URI [PROCESSOR_URI ...]
                        Specify one or more image processor actions to preform on the inpaint mask image
                        specified by --image-seeds. For example: --mask-image-processors "invert". To
                        obtain more information about what image processors are available and how to use
                        them, see: --image-processor-help.
  -cip PROCESSOR_URI [PROCESSOR_URI ...], --control-image-processors PROCESSOR_URI [PROCESSOR_URI ...]
                        Specify one or more image processor actions to preform on the control image
                        specified by --image-seeds, this option is meant to be used with --control-nets.
                        Example: --control-image-processors "canny;lower=50;upper=100". The delimiter
                        "+" can be used to specify a different processor group for each image when using
                        multiple control images with --control-nets. For example if you have --image-
                        seeds "img1.png, img2.png" or --image-seeds "...;control=img1.png, img2.png"
                        specified and multiple ControlNet models specified with --control-nets, you can
                        specify processors for those control images with the syntax: (--control-image-
                        processors "processes-img1" + "processes-img2"), this syntax also supports
                        chaining of processors, for example: (--control-image-processors "first-process-
                        img1" "second-process-img1" + "process-img2"). The amount of specified
                        processors must not exceed the amount of specified control images, or you will
                        receive a syntax error message. Images which do not have a processor defined for
                        them will not be processed, and the plus character can be used to indicate an
                        image is not to be processed and instead skipped over when that image is a
                        leading element, for example (--control-image-processors + "process-second")
                        would indicate that the first control guidance image is not to be processed,
                        only the second. To obtain more information about what image processors are
                        available and how to use them, see: --image-processor-help.
  --image-processor-help [PROCESSOR_NAME ...]
                        Use this option alone (or with --plugin-modules) and no model specification in
                        order to list available image processor module names. Specifying one or more
                        module names after this option will cause usage documentation for the specified
                        modules to be printed.
  -pp PROCESSOR_URI [PROCESSOR_URI ...], --post-processors PROCESSOR_URI [PROCESSOR_URI ...]
                        Specify one or more image processor actions to preform on generated output
                        before it is saved. For example: --post-processors
                        "upcaler;model=4x_ESRGAN.pth". To obtain more information about what processors
                        are available and how to use them, see: --image-processor-help.
  -iss FLOAT [FLOAT ...], --image-seed-strengths FLOAT [FLOAT ...]
                        One or more image strength values to try when using --image-seeds for img2img or
                        inpaint mode. Closer to 0 means high usage of the seed image (less noise
                        convolution), 1 effectively means no usage (high noise convolution). Low values
                        will produce something closer or more relevant to the input image, high values
                        will give the AI more creative freedom. (default: [0.8])
  -uns INTEGER [INTEGER ...], --upscaler-noise-levels INTEGER [INTEGER ...]
                        One or more upscaler noise level values to try when using the super resolution
                        upscaler --model-type torch-upscaler-x4. Specifying this option for --model-type
                        torch-upscaler-x2 will produce an error message. The higher this value the more
                        noise is added to the image before upscaling (similar to --image-seed-
                        strengths). (default: [20])
  -gs FLOAT [FLOAT ...], --guidance-scales FLOAT [FLOAT ...]
                        One or more guidance scale values to try. Guidance scale effects how much your
                        text prompt is considered. Low values draw more data from images unrelated to
                        text prompt. (default: [5])
  -igs FLOAT [FLOAT ...], --image-guidance-scales FLOAT [FLOAT ...]
                        One or more image guidance scale values to try. This can push the generated
                        image towards the initial image when using --model-type *-pix2pix models, it is
                        unsupported for other model types. Use in conjunction with --image-seeds,
                        inpainting (masks) and --control-nets are not supported. Image guidance scale is
                        enabled by setting image-guidance-scale > 1. Higher image guidance scale
                        encourages generated images that are closely linked to the source image, usually
                        at the expense of lower image quality. Requires a value of at least 1. (default:
                        [1.5])
  -gr FLOAT [FLOAT ...], --guidance-rescales FLOAT [FLOAT ...]
                        One or more guidance rescale factors to try. Proposed by [Common Diffusion Noise
                        Schedules and Sample Steps are Flawed](https://arxiv.org/pdf/2305.08891.pdf)
                        "guidance_scale" is defined as "φ" in equation 16. of [Common Diffusion Noise
                        Schedules and Sample Steps are Flawed] (https://arxiv.org/pdf/2305.08891.pdf).
                        Guidance rescale factor should fix overexposure when using zero terminal SNR.
                        This is supported for basic text to image generation when using --model-type
                        "torch" but not inpainting, img2img, or --control-nets. When using --model-type
                        "torch-sdxl" it is supported for basic generation, inpainting, and img2img,
                        unless --control-nets is specified in which case only inpainting is supported.
                        It is supported for --model-type "torch-sdxl-pix2pix" but not --model-type
                        "torch-pix2pix". (default: [0.0])
  -ifs INTEGER [INTEGER ...], --inference-steps INTEGER [INTEGER ...]
                        One or more inference steps values to try. The amount of inference (de-noising)
                        steps effects image clarity to a degree, higher values bring the image closer to
                        what the AI is targeting for the content of the image. Values between 30-40
                        produce good results, higher values may improve image quality and or change
                        image content. (default: [30])

Linux or WSL Install

First update your system and install build-essential

sudo apt update && sudo apt upgrade
sudo apt install build-essential

Install CUDA Toolkit 12.*: https://developer.nvidia.com/cuda-downloads

I recommend using the runfile option:

# CUDA Toolkit 12.2.1 For Ubuntu / Debian / WSL

wget https://developer.download.nvidia.com/compute/cuda/12.2.1/local_installers/cuda_12.2.1_535.86.10_linux.run

Run dgenerate to generate images:

# Images are output to the "output" folder
# in the current working directory by default

dgenerate --help

dgenerate stabilityai/stable-diffusion-2-1 \
--prompts "an astronaut riding a horse" \
--output-path output \
--inference-steps 40 \
--guidance-scales 10

Basic Usage

The example below attempts to generate an astronaut riding a horse using 5 different random seeds, 3 different inference steps values, and 3 different guidance scale values.

It utilizes the “stabilityai/stable-diffusion-2-1” model repo on Hugging Face.

45 uniquely named images will be generated (5 x 3 x 3)

Also Adjust output size to 512x512 and output generated images to the “astronaut” folder in the current working directory.

When --output-path is not specified, the default output location is the “output” folder in the current working directory, if the path that is specified does not exist then it will be created.

dgenerate stabilityai/stable-diffusion-2-1 \
--prompts "an astronaut riding a horse" \
--gen-seeds 5 \
--output-path astronaut \
--inference-steps 30 40 50 \
--guidance-scales 5 7 10 \
--output-size 512x512

Loading models from huggingface blob links is also supported:

dgenerate https://huggingface.co/stabilityai/stable-diffusion-2-1/blob/main/v2-1_768-ema-pruned.safetensors \
--prompts "an astronaut riding a horse" \
--gen-seeds 5 \
--output-path astronaut \
--inference-steps 30 40 50 \
--guidance-scales 5 7 10 \
--output-size 512x512

SDXL is supported and can be used to generate highly realistic images.

Prompt only generation, img2img, and inpainting is supported for SDXL.

Refiner models can be specified, fp16 model variant and a datatype of float16 is recommended to prevent out of memory conditions on the average GPU :)

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--sdxl-high-noise-fractions 0.6 0.7 0.8 \
--gen-seeds 5 \
--inference-steps 50 \
--guidance-scales 12 \
--sdxl-refiner stabilityai/stable-diffusion-xl-refiner-1.0 \
--prompts "real photo of an astronaut riding a horse on the moon" \
--variant fp16 --dtype float16 \
--output-size 1024

Negative Prompt

In order to specify a negative prompt, each prompt argument is split into two parts separated by ;

The prompt text occurring after ; is the negative influence prompt.

To attempt to avoid rendering of a saddle on the horse being ridden, you could for example add the negative prompt “saddle” or “wearing a saddle” or “horse wearing a saddle” etc.

dgenerate stabilityai/stable-diffusion-2-1 \
--prompts "an astronaut riding a horse; horse wearing a saddle" \
--gen-seeds 5 \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512

Multiple Prompts

Multiple prompts can be specified one after another in quotes in order to generate images using multiple prompt variations.

The following command generates 10 uniquely named images using two prompts and five random seeds (2x5)

5 of them will be from the first prompt and 5 of them from the second prompt.

All using 50 inference steps, and 10 for guidance scale value.

dgenerate stabilityai/stable-diffusion-2-1 \
--prompts "an astronaut riding a horse" "an astronaut riding a donkey" \
--gen-seeds 5 \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512

Image Seed

The --image-seeds argument can be used to specify one or more image input resource groups for use in rendering, and allows for the specification of img2img source images, inpaint masks, control net guidance images, deep floyd stage images, image group resizing, and frame slicing values for animations. It possesses it’s own URI syntax for defining different image inputs used for image generation, the example described below is the simplest case for one image input (img2img).

This example uses a photo of Buzz Aldrin on the moon to generate a photo of an astronaut standing on mars using img2img, this uses an image seed downloaded from wikipedia.

Disk file paths may also be used for image seeds and generally that is the standard use case, multiple image seed definitions may be provided and images will be generated from each image seed individually.

# Generate this image using 5 different seeds, 3 different inference-step values, 3 different
# guidance-scale values as above.

# In addition this image will be generated using 3 different image seed strengths.

# Adjust output size to 512x512 and output generated images to 'astronaut' folder, the image seed
# will be resized to that dimension with aspect ratio respected by default, the width is fixed and
# the height will be calculated, this behavior can be changed globally with the --no-aspect option

--image-seeds serves as the entire mechanism for determining if img2img or inpainting is going to occur via it’s URI syntax described further in the section Inpainting.

In addition to this it can be used to provide control guidance images in the case of txt2img, img2img, or inpainting via the use of a URI syntax involving keyword arguments.

The syntax --image-seeds "my-image-seed.png;control=my-control-image.png" can be used with --control-nets to specify img2img mode with a ControlNet for example, see: Specifying Control Nets for more information.

Inpainting

Inpainting on an image can be preformed by providing a mask image with your image seed. This mask should be a black and white image of identical size to your image seed. White areas of the mask image will be used to tell the AI what areas of the seed image should be filled in with generated content.

For using inpainting on animated image seeds, jump to: Inpainting Animations

Some possible definitions for inpainting are:

  • --image-seeds "my-image-seed.png;my-mask-image.png"

  • --image-seeds "my-image-seed.png;mask=my-mask-image.png"

The format is your image seed and mask image separated by ;, optionally mask can be named argument. The alternate syntax is for disambiguation when preforming img2img or inpainting operations while Specifying Control Nets or other operations where keyword arguments might be necessary for disambiguation such as per image seed Animation Slicing, and the specification of the image from a previous Deep Floyd stage using the floyd argument.

Mask images can be downloaded from URL’s just like any other resource mentioned in an --image-seeds definition, however for this example files on disk are used for brevity.

You can download them here:

The command below generates a cat sitting on a bench with the images from the links above, the mask image masks out areas over the dog in the original image, causing the dog to be replaced with an AI generated cat.

--prompts "Face of a yellow cat, high resolution, sitting on a park bench" \
--image-seed-strengths 0.8 \
--guidance-scales 10 \
--inference-steps 100

Per Image Seed Resizing

If you want to specify multiple image seeds that will have different output sizes irrespective of their input size or a globally defined output size defined with --output-size, You can specify their output size individually at the end of each provided image seed.

This will work when using a mask image for inpainting as well, including when using animated inputs.

This also works when Specifying Control Nets and guidance images for control nets.

Here are some possible definitions:

  • --image-seeds "my-image-seed.png;512x512" (img2img)

  • --image-seeds "my-image-seed.png;my-mask-image.png;512x512" (inpainting)

  • --image-seeds "my-image-seed.png;resize=512x512" (img2img)

  • --image-seeds "my-image-seed.png;mask=my-mask-image.png;resize=512x512" (inpainting)

The alternate syntax with named arguments is for disambiguation when Specifying Control Nets, or preforming per image seed Animation Slicing, or specifying the previous Deep Floyd stage output with the floyd keyword argument.

When one dimension is specified, that dimension is the width, and the height.

The height of an image is calculated to be aspect correct by default for all resizing methods unless --no-aspect has been given as an argument on the command line or the aspect keyword argument is used in the --image-seeds definition.

The the aspect correct resize behavior can be controlled on a per image seed definition basis using the aspect keyword argument. Any value given to this argument overrides the presence or absense of the --no-aspect command line argument.

the aspect keyword argument can only be used when all other components of the image seed definition are defined using keyword arguments. aspect=false disables aspect correct resizing, and aspect=true enables it.

Some possible definitions:

  • --image-seeds "my-image-seed.png;resize=512x512;aspect=false" (img2img)

  • --image-seeds "my-image-seed.png;mask=my-mask-image.png;resize=512x512;aspect=false" (inpainting)

The following example preforms img2img generation, followed by inpainting generation using 2 image seed definitions. The involved images are resized using the basic syntax with no keyword arguments present in the image seeds.

dgenerate stabilityai/stable-diffusion-2-1 \
--image-seeds "my-image-seed.png;1024" "my-image-seed.png;my-mask-image.png;512x512" \
--prompts "Face of a yellow cat, high resolution, sitting on a park bench" \
--image-seed-strengths 0.8 \
--guidance-scales 10 \
--inference-steps 100

Animated Output

dgenerate supports many video formats through the use of PyAV (ffmpeg), as well as GIF & WebP.

See --help for information about all formats supported for the --animation-format option.

When an animated image seed is given, animated output will be produced in the format of your choosing.

In addition, every frame will be written to the output folder as a uniquely named image.

By specifying --animation-format frames you can tell dgenerate that you just need the frame images and not to produce any coalesced animation file for you. You may also specify --no-frames to indicate that you only want an animation file to be produced and no intermediate frames, though using this option with --animation-format frames is considered an error.

If the animation is not 1:1 aspect ratio, the width will be fixed to the width of the requested output size, and the height calculated to match the aspect ratio of the animation. Unless --no-aspect or the --image-seeds keyword argument aspect=false are specified, in which case the video will be resized to the requested dimension exactly.

If you do not set an output size, the size of the input animation will be used.

# Use a GIF of a man riding a horse to create an animation of an astronaut riding a horse.

dgenerate stabilityai/stable-diffusion-2-1 \
--prompts "an astronaut riding a horse" \

--image-seed-strengths 0.5 \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512 \
--animation-format mp4

The above syntax is the same syntax used for generating an animation with a control image when --control-nets is used.

Animations can also be generated using an alternate syntax for --image-seeds that allows the specification of a control image source when it is desired to use --control-nets with img2img or inpainting.

For more information about this see: Specifying Control Nets

As well as the information about --image-seeds from dgenerates --help output.

Animation Slicing

Animated inputs can be sliced by a frame range either globally using --frame-start and --frame-end or locally using the named argument syntax for --image-seeds, for example:

  • --image-seeds "animated.gif;frame-start=3;frame-end=10".

When using animation slicing at the --image-seed level, all image input definitions other than the main image must be specified using keyword arguments.

For example here are some possible definitions:

  • --image-seeds "seed.gif;frame-start=3;frame-end=10"

  • --image-seeds "seed.gif;mask=mask.gif;frame-start=3;frame-end=10

  • --image-seeds "seed.gif;control=control-guidance.gif;frame-start=3;frame-end=10

  • --image-seeds "seed.gif;mask=mask.gif;control=control-guidance.gif;frame-start=3;frame-end=10

  • --image-seeds "seed.gif;floyd=stage1.gif;frame-start=3;frame-end=10"

  • --image-seeds "seed.gif;mask=mask.gif;floyd=stage1.gif;frame-start=3;frame-end=10"

Specifying a frame slice locally in an image seed overrides the global frame slice setting defined by --frame-start or --frame-end, and is specific only to that image seed, other image seed definitions will not be affected.

Perhaps you only want to run diffusion on the first frame of an animated input in order to save time in finding good parameters for generating every frame. You could slice to only the first frame using --frame-start 0 --frame-end 0, which will be much faster than rendering the entire video/gif outright.

The slice range zero indexed and also inclusive, inclusive means that the starting and ending frames specified by --frame-start and --frame-end will be included in the slice. Both slice points do not have to be specified at the same time. You can exclude the tail end of a video with just --frame-end alone, or seek to a certain start frame in the video with --frame-start alone and render from there onward, this applies for keyword arguments in the --image-seeds definition as well.

If your slice only results in the processing of a single frame, an animated file format will not be generated, only a single image output will be generated for that image seed during the generation step.

Inpainting Animations

Image seeds can be supplied an animated or static image mask to define the areas for inpainting while generating an animated output.

Any possible combination of image/video parameters can be used. The animation with least amount of frames in the entire specification determines the frame count, and any static images present are duplicated across the entire animation. The first animation present in an image seed specification always determines the output FPS of the animation.

When an animated seed is used with an animated mask, the mask for every corresponding frame in the input is taken from the animated mask, the runtime of the animated output will be equal to the shorter of the two animated inputs. IE: If the seed animation and the mask animation have different length, the animated output is clipped to the length of the shorter of the two.

When a static image is used as a mask, that image is used as an inpaint mask for every frame of the animated seed.

When an animated mask is used with a static image seed, the animated output length is that of the animated mask. A video is created by duplicating the image seed for every frame of the animated mask, the animated output being generated by masking them together.

Deterministic Output

If you generate an image you like using a random seed, you can later reuse that seed in another generation.

Updates to the backing model may affect determinism in the generation.

Output images have a name format that starts with the seed, IE: s_(seed here)_ ...png

Reusing a seed has the effect of perfectly reproducing the image in the case that all other parameters are left alone, including the model version.

You can output a configuration file for each image / animation produced that will reproduce it exactly using the option --output-configs, that same information can be written to the metadata of generated PNG files using the option --output-metadata and can be read back with ImageMagick for example as so:

magick identify -format "%[Property:DgenerateConfig] generated_file.png

Generated configuration can be read back into dgenerate via a pipe or file redirection.

magick identify -format "%[Property:DgenerateConfig] generated_file.png | dgenerate

dgenerate < generated-config.txt

Specifying a seed directly and changing the prompt slightly, or parameters such as image seed strength if using a seed image, guidance scale, or inference steps, will allow for generating variations close to the original image which may possess all of the original qualities about the image that you liked as well as additional qualities. You can further manipulate the AI into producing results that you want with this method.

Changing output resolution will drastically affect image content when reusing a seed to the point where trying to reuse a seed with a different output size is pointless.

The following command demonstrates manually specifying two different seeds to try: 1234567890, and 9876543210

dgenerate stabilityai/stable-diffusion-2-1 \
--prompts "an astronaut riding a horse" \
--seeds 1234567890 9876543210 \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512

Specifying a specific GPU for CUDA

The desired GPU to use for CUDA acceleration can be selected using --device cuda:N where N is the device number of the GPU as reported by nvidia-smi.

# Console 1, run on GPU 0

dgenerate stabilityai/stable-diffusion-2-1 \
--prompts "an astronaut riding a horse" \
--output-path astronaut_1 \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512 \
--device cuda:0

# Console 2, run on GPU 1 in parallel

dgenerate stabilityai/stable-diffusion-2-1 \
--prompts "an astronaut riding a cow" \
--output-path astronaut_2 \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512 \
--device cuda:1

Specifying a Scheduler (sampler)

A scheduler (otherwise known as a sampler) for the main model can be selected via the use of --scheduler.

And in the case of SDXL the refiner’s scheduler can be selected independently with --sdxl-refiner-scheduler.

The refiner scheduler defaults to the value of --scheduler, which in turn defaults to automatic selection.

Available schedulers for a specific combination of dgenerate arguments can be queried using --scheduler help, or --sdxl-refiner-scheduler help, though both cannot be queried simultaneously.

In order to use the query feature it is ideal that you provide all the other arguments that you plan on using while making the query, as different combinations of arguments will result in different underlying pipeline implementations being created, each of which may have different compatible scheduler names listed. The model needs to be loaded in order to gather this information.

For example there is only one compatible scheduler for this upscaler configuration:

dgenerate stabilityai/sd-x2-latent-upscaler --variant fp16 --dtype float16 \
--model-type torch-upscaler-x2 \
--prompts "none" \
--image-seeds my-image.png \
--output-size 256 \
--scheduler help

# Outputs:
#
# Compatible schedulers for "stabilityai/sd-x2-latent-upscaler" are:
#
#    "EulerDiscreteScheduler"

Typically however, there will be many compatible schedulers:

dgenerate stabilityai/stable-diffusion-2 \
--inference-steps 40 \
--guidance-scales 8 \
--output-size 1024 \
--gen-seeds 2 \
--prompts "none" \
--scheduler help

# Outputs:
#
# Compatible schedulers for "stabilityai/stable-diffusion-2" are:
#
#    "EulerDiscreteScheduler"
#    "HeunDiscreteScheduler"
#    "UniPCMultistepScheduler"
#    "DDPMScheduler"
#    "EulerDiscreteScheduler"
#    "DDIMScheduler"
#    "DEISMultistepScheduler"
#    "LMSDiscreteScheduler"
#    "DPMSolverMultistepScheduler"
#    "EulerAncestralDiscreteScheduler"
#    "DPMSolverSinglestepScheduler"
#    "DPMSolverSDEScheduler"
#    "KDPM2DiscreteScheduler"
#    "PNDMScheduler"
#    "KDPM2AncestralDiscreteScheduler"
#    "LCMScheduler"

Specifying a VAE

To specify a VAE directly use --vae.

The URI syntax for --vae is AutoEncoderClass;model=(huggingface repository slug/blob link or file/folder path)

Named arguments when loading a VAE are separated by the ; character and are not positional, meaning they can be defined in any order.

Loading arguments available when specifying a VAE for torch --model-type values are: model, revision, variant, subfolder, and dtype

Loading arguments available when specifying VAE for flax --model-type values are: model, revision, subfolder, dtype

The only named arguments compatible with loading a .safetensors or other model file directly off disk are model and dtype

The other named arguments are available when loading from a huggingface repository or folder that may or may not be a local git repository on disk.

Available encoder classes for torch models are:

  • AutoencoderKL

  • AsymmetricAutoencoderKL (Does not support --vae-slicing or --vae-tiling)

  • AutoencoderTiny

  • ConsistencyDecoderVAE

Available encoder classes for flax models are:

  • FlaxAutoencoderKL (Does not support --vae-slicing or --vae-tiling)

The AutoencoderKL encoder class accepts huggingface repository slugs/blob links, .pt, .pth, .bin, .ckpt, and .safetensors files. Other encoders can only accept huggingface repository slugs/blob links, or a path to a folder on disk with the model configuration and model file(s).

dgenerate stabilityai/stable-diffusion-2-1 \
--vae "AutoencoderKL;model=stabilityai/sd-vae-ft-mse" \
--prompts "an astronaut riding a horse" \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512

If you want to select the repository revision, such as main etc, use the named argument revision, subfolder is required in this example as well because the VAE model file exists in a subfolder of the specified huggingface repository.

dgenerate stabilityai/stable-diffusion-2-1 \
--revision fp16 \
--dtype float16 \
--vae "AutoencoderKL;model=stabilityai/stable-diffusion-2-1;revision=fp16;subfolder=vae" \
--prompts "an astronaut riding a horse" \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512

If you wish to specify a weights variant IE: load pytorch_model.<variant>.safetensors, from a huggingface repository that has variants of the same model, use the named argument variant. This usage is only valid when loading VAEs if --model-type is either torch or torch-sdxl. Attempting to use it with FlaxAutoencoderKL with produce an error message. When not specified in the URI, this value does NOT default to the value --variant to prevent errors during common use cases. If you wish to select a variant you must specify it in the URI.

dgenerate stabilityai/stable-diffusion-2-1 \
--variant fp16 \
--vae "AutoencoderKL;model=stabilityai/stable-diffusion-2-1;subfolder=vae;variant=fp16" \
--prompts "an astronaut riding a horse" \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512

If your weights file exists in a subfolder of the repository, use the named argument subfolder

dgenerate stabilityai/stable-diffusion-2-1 \
--vae "AutoencoderKL;model=stabilityai/stable-diffusion-2-1;subfolder=vae" \
--prompts "an astronaut riding a horse" \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512

If you want to specify the model precision, use the named argument dtype, accepted values are the same as --dtype, IE: ‘float32’, ‘float16’, ‘auto’

dgenerate stabilityai/stable-diffusion-2-1 \
--revision fp16 \
--dtype float16 \
--vae "AutoencoderKL;model=stabilityai/stable-diffusion-2-1;revision=fp16;subfolder=vae;dtype=float16" \
--prompts "an astronaut riding a horse" \
--output-path astronaut \
--inference-steps 50 \
--guidance-scales 10 \
--output-size 512x512

If you are loading a .safetensors or other file from a path on disk, only the model, and dtype arguments are available.

# These are only syntax examples

dgenerate huggingface/diffusion_model \
--vae "AutoencoderKL;model=my_vae.safetensors" \
--prompts "Syntax example"

dgenerate huggingface/diffusion_model \
--vae "AutoencoderKL;model=my_vae.safetensors;dtype=float16" \
--prompts "Syntax example"

VAE Tiling and Slicing

You can use --vae-tiling and --vae-slicing to enable to generation of huge images without running your GPU out of memory. Note that if you are using --control-nets you may still be memory limited by the size of the image being processed by the ControlNet, and still may run in to memory issues with large image inputs.

When --vae-tiling is used, the VAE will split the input tensor into tiles to compute decoding and encoding in several steps. This is useful for saving a large amount of memory and to allow processing larger images.

When --vae-slicing is used, the VAE will split the input tensor in slices to compute decoding in several steps. This is useful to save some memory, especially when --batch-size is greater than 1.

# Here is an SDXL example of high resolution image generation utilizing VAE tiling/slicing

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--variant fp16 --dtype float16 \
--vae "AutoencoderKL;model=madebyollin/sdxl-vae-fp16-fix" \

--guidance-scales 8 \
--output-size 2048 \
--sdxl-target-size 2048 \
--prompts "Photo of a horse standing near the open door of a red barn, high resolution; artwork"

Specifying a UNet

An alternate UNet model can be specified via a URI with the --unet option, in a similar fashion to --vae and other model arguments that accept URIs.

This is useful in particular for using the latent consistency scheduler.

The first component of the --unet URI is the model path itself.

You can provide a path to a huggingface repo, or a folder on disk (downloaded huggingface repository).

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--variant fp16 --dtype float16 \
--unet latent-consistency/lcm-sdxl \
--scheduler LCMScheduler \
--inference-steps 4 \
--guidance-scales 8 \
--gen-seeds 2 \
--output-size 1024 \
--prompts "a close-up picture of an old man standing in the rain"

Loading arguments available when specifying a UNet for torch --model-type values are: revision, variant, subfolder, and dtype

In the case of --unet the variant loading argument defaults to the value of --variant if you do not specify it in the URI.

Loading arguments available when specifying UNet for flax --model-type values are: revision, subfolder, dtype. variant is not used for flax.

The --unet2 option can be used to specify a UNet for the SDXL Refiner or Stable Cascade Decoder, and uses the same syntax as --unet.

Specifying an SDXL Refiner

When the main model is an SDXL model and --model-type torch-sdxl is specified, you may specify a refiner model with --sdxl-refiner.

You can provide a path to a huggingface repo/blob link, folder on disk, or a model file on disk such as a .pt, .pth, .bin, .ckpt, or .safetensors file.

This argument is parsed in much the same way as the argument --vae, except the model is the first value specified.

Loading arguments available when specifying a refiner are: revision, variant, subfolder, and dtype

The only named argument compatible with loading a .safetensors or other file directly off disk is dtype

The other named arguments are available when loading from a huggingface repo/blob link, or folder that may or may not be a local git repository on disk.

# Basic usage of SDXL with a refiner

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \

--inference-steps 40 \
--guidance-scales 8 \
--output-size 1024 \
--prompts "Photo of a horse standing near the open door of a red barn, high resolution; artwork"

If you want to select the repository revision, such as main etc, use the named argument revision

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--variant fp16 --dtype float16 \
--sdxl-refiner "stabilityai/stable-diffusion-xl-refiner-1.0;revision=main" \

--inference-steps 40 \
--guidance-scales 8 \
--output-size 1024 \
--prompts "Photo of a horse standing near the open door of a red barn, high resolution; artwork"

If you wish to specify a weights variant IE: load pytorch_model.<variant>.safetensors, from a huggingface repository that has variants of the same model, use the named argument variant. By default this value is the same as --variant unless you override it.

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--variant fp16 --dtype float16 \
--sdxl-refiner "stabilityai/stable-diffusion-xl-refiner-1.0;variant=fp16" \

--inference-steps 40 \
--guidance-scales 8 \
--output-size 1024 \
--prompts "Photo of a horse standing near the open door of a red barn, high resolution; artwork"

If your weights file exists in a subfolder of the repository, use the named argument subfolder

# This is a non working example as I do not know of a repo with an SDXL refiner
# in a subfolder :) this is only a syntax example

dgenerate huggingface/sdxl_model --model-type torch-sdxl \
--variant fp16 --dtype float16 \
--sdxl-refiner "huggingface/sdxl_refiner;subfolder=repo_subfolder"

If you want to select the model precision, use the named argument dtype. By default this value is the same as --dtype unless you override it. Accepted values are the same as --dtype, IE: ‘float32’, ‘float16’, ‘auto’

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--variant fp16 --dtype float16 \
--sdxl-refiner "stabilityai/stable-diffusion-xl-refiner-1.0;dtype=float16" \
--sdxl-high-noise-fractions 0.8 \
--inference-steps 40 \
--guidance-scales 8 \
--output-size 1024 \
--prompts "Photo of a horse standing near the open door of a red barn, high resolution; artwork"

If you are loading a .safetensors or other file from a path on disk, simply do:

# This is only a syntax example

dgenerate huggingface/sdxl_model --model-type torch-sdxl \
--sdxl-refiner my_refinermodel.safetensors

When preforming inpainting or when using ControlNets, the refiner will automatically operate in edit mode instead of cooperative denoising mode. Edit mode can be forced in other situations with the option --sdxl-refiner-edit.

Edit mode means that the refiner model is accepting the fully (or mostly) denoised output of the main model generated at the full number of inference steps specified, and acting on it with an image strength (image seed strength) determined by (1.0 - high-noise-fraction).

The output latent from the main model is renoised with a certain amount of noise determined by the strength, a lower number means less noise and less modification of the latent output by the main model.

This is similar to what happens when using dgenerate in img2img with a standalone model, technically it is just img2img, however refiner models are better at enhancing details from the main model in this use case.

Specifying a Stable Cascade Decoder

When the main model is a Stable Cascade prior model and --model-type torch-s-cascade is specified, you may specify a decoder model with --s-cascade-decoder.

The syntax (and URI arguments) for specifying the decoder model is identical to specifying an SDXL refiner model as mentioned above.

dgenerate stabilityai/stable-cascade-prior \
--model-type torch-s-cascade \
--variant bf16 \
--dtype bfloat16 \
--model-cpu-offload \
--s-cascade-decoder-cpu-offload \
--s-cascade-decoder "stabilityai/stable-cascade;dtype=float16" \
--inference-steps 20 \
--guidance-scales 4 \
--s-cascade-decoder-inference-steps 10 \
--s-cascade-decoder-guidance-scales 0 \
--gen-seeds 2 \
--prompts "an image of a shiba inu, donning a spacesuit and helmet"

Specifying LoRAs

It is possible to specify one or more LoRA models using --loras

When multiple specifications are given, all mentioned models will be fused into the main model at a given scale.

The plural form of the argument is identical to the non-plural version, which only exists for backward compatibility.

You can provide a huggingface repository slug, .pt, .pth, .bin, .ckpt, or .safetensors files. Blob links are not accepted, for that use subfolder and weight-name described below.

The LoRA scale can be specified after the model path by placing a ; (semicolon) and then using the named argument scale

When a scale is not specified, 1.0 is assumed.

Named arguments when loading a LoRA are separated by the ; character and are not positional, meaning they can be defined in any order.

Loading arguments available when specifying a LoRA are: scale, revision, subfolder, and weight-name

The only named argument compatible with loading a .safetensors or other file directly off disk is scale

The other named arguments are available when loading from a huggingface repository or folder that may or may not be a local git repository on disk.

This example shows loading a LoRA using a huggingface repository slug and specifying scale for it.

# Don't expect great results with this example,
# Try models and LoRA's downloaded from CivitAI

dgenerate runwayml/stable-diffusion-v1-5 \
--loras "pcuenq/pokemon-lora;scale=0.5" \
--prompts "Gengar standing in a field at night under a full moon, highquality, masterpiece, digital art" \
--inference-steps 40 \
--guidance-scales 10 \
--gen-seeds 5 \
--output-size 800

Specifying the file in a repository directly can be done with the named argument weight-name

Shown below is an SDXL compatible LoRA being used with the SDXL base model and a refiner.

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--inference-steps 30 \
--sdxl-refiner stabilityai/stable-diffusion-xl-refiner-1.0 \
--prompts "sketch of a horse by Leonardo da Vinci" \
--variant fp16 --dtype float16 \
--loras "goofyai/SDXL-Lora-Collection;scale=1.0;weight-name=leonardo_illustration.safetensors" \
--output-size 1024

If you want to select the repository revision, such as main etc, use the named argument revision

dgenerate runwayml/stable-diffusion-v1-5 \
--loras "pcuenq/pokemon-lora;scale=0.5;revision=main" \
--prompts "Gengar standing in a field at night under a full moon, highquality, masterpiece, digital art" \
--inference-steps 40 \
--guidance-scales 10 \
--gen-seeds 5 \
--output-size 800

If your weights file exists in a subfolder of the repository, use the named argument subfolder

# This is a non working example as I do not know of a repo with a LoRA weight in a subfolder :)
# This is only a syntax example

dgenerate huggingface/model \
--prompts "Syntax example" \
--loras "huggingface/lora_repo;scale=1.0;subfolder=repo_subfolder;weight-name=lora_weights.safetensors"

If you are loading a .safetensors or other file from a path on disk, only the scale argument is available.

# This is only a syntax example

dgenerate runwayml/stable-diffusion-v1-5 \
--prompts "Syntax example" \
--loras "my_lora.safetensors;scale=1.0"

Specifying Textual Inversions

One or more Textual Inversion models may be specified with --textual-inversions

You can provide a huggingface repository slug, .pt, .pth, .bin, .ckpt, or .safetensors files. Blob links are not accepted, for that use subfolder and weight-name described below.

Arguments pertaining to the loading of each textual inversion model may be specified in the same way as when using --loras minus the scale argument.

Available arguments are: revision, subfolder, and weight-name

Named arguments are available when loading from a huggingface repository or folder that may or may not be a local git repository on disk, when loading directly from a .safetensors file or other file from a path on disk they should not be used.

# Load a textual inversion from a huggingface repository specifying it's name in the repository
# as an argument

dgenerate Duskfallcrew/isometric-dreams-sd-1-5  \
--textual-inversions "Duskfallcrew/IsometricDreams_TextualInversions;weight-name=Isometric_Dreams-1000.pt" \
--scheduler KDPM2DiscreteScheduler \
--inference-steps 30 \
--guidance-scales 7 \
--prompts "a bright photo of the Isometric_Dreams, a tv and a stereo in it and a book shelf, a table, a couch,a room with a bed"

If you want to select the repository revision, such as main etc, use the named argument revision

# This is a non working example as I do not know of a repo that utilizes revisions with
# textual inversion weights :) this is only a syntax example

dgenerate huggingface/model \
--prompts "Syntax example" \
--textual-inversions "huggingface/ti_repo;revision=main"

If your weights file exists in a subfolder of the repository, use the named argument subfolder

# This is a non working example as I do not know of a repo with a textual
# inversion weight in a subfolder :) this is only a syntax example

dgenerate huggingface/model \
--prompts "Syntax example" \
--textual-inversions "huggingface/ti_repo;subfolder=repo_subfolder;weight-name=ti_model.safetensors"

If you are loading a .safetensors or other file from a path on disk, simply do:

# This is only a syntax example

dgenerate runwayml/stable-diffusion-v1-5 \
--prompts "Syntax example" \
--textual-inversions "my_ti_model.safetensors"

Specifying Control Nets

One or more ControlNet models may be specified with --control-nets, and multiple control net guidance images can be specified via --image-seeds in the case that you specify multiple control net models.

You can provide a huggingface repository slug / blob link, .pt, .pth, .bin, .ckpt, or .safetensors files.

Control images for the Control Nets can be provided using --image-seeds

When using --control-nets specifying control images via --image-seeds can be accomplished in these ways:

  • --image-seeds "control-image.png" (txt2img)

  • --image-seeds "img2img-seed.png;control=control-image.png" (img2img)

  • --image-seeds "img2img-seed.png;mask=mask.png;control=control-image.png" (inpainting)

Multiple control image sources can be specified in these ways when using multiple control nets:

  • --image-seeds "control-1.png, control-2.png" (txt2img)

  • --image-seeds "img2img-seed.png;control=control-1.png, control-2.png" (img2img)

  • --image-seeds "img2img-seed.png;mask=mask.png;control=control-1.png, control-2.png" (inpainting)

It is considered a syntax error if you specify a non-equal amount of control guidance images and --control-nets URIs and you will receive an error message if you do so.

resize=WIDTHxHEIGHT can be used to select a per --image-seeds resize dimension for all image sources involved in that particular specification, as well as aspect=true/false and the frame slicing arguments frame-start and frame-end.

ControlNet guidance images may actually be animations such as MP4s, GIFs etc. Frames can be taken from multiple videos simultaneously. Any possible combination of image/video parameters can be used. The animation with least amount of frames in the entire specification determines the frame count, and any static images present are duplicated across the entire animation. The first animation present in an image seed specification always determines the output FPS of the animation.

Arguments pertaining to the loading of each ControlNet model specified with --control-nets may be declared in the same way as when using --vae with the addition of a scale argument and from_torch argument when using flax --model-type values.

Available arguments when using torch --model-type values are: scale, start, end, revision, variant, subfolder, dtype

Available arguments when using flax --model-type values are: scale, revision, subfolder, dtype, from_torch

Most named arguments apply to loading from a huggingface repository or folder that may or may not be a local git repository on disk, when loading directly from a .safetensors file or other file from a path on disk the available arguments are scale, start, end, and from_torch. from_torch can be used with flax for loading pytorch models from .pt or other files designed for torch from a repo or file/folder on disk.

The scale argument indicates the affect scale of the control net model.

For torch, the start argument indicates at what fraction of the total inference steps at which the control net model starts to apply guidance. If you have multiple control net models specified, they can apply guidance over different segments of the inference steps using this option, it defaults to 0.0, meaning start at the first inference step.

for torch, the end argument indicates at what fraction of the total inference steps at which the control net model stops applying guidance. It defaults to 1.0, meaning stop at the last inference step.

These examples use: vermeer_canny_edged.png

# inversion weight in a subfolder :) this is only a syntax example

dgenerate huggingface/model \
--prompts "Syntax example" \
--control-nets "huggingface/cn_repo;subfolder=repo_subfolder"

If you are loading a .safetensors or other file from a path on disk, simply do:

# This is only a syntax example

dgenerate runwayml/stable-diffusion-v1-5 \
--prompts "Syntax example" \
--control-nets "my_cn_model.safetensors"

Specifying Generation Batch Size

Multiple image variations from the same seed can be produce on a GPU simultaneously using the --batch-size option of dgenerate. This can be used in combination with --batch-grid-size to output image grids if desired.

When not writing to image grids the files in the batch will be written to disk with the suffix _image_N where N is index of the image in the batch of images that were generated.

When producing an animation, you can either write N animation output files with the filename suffixes _animation_N where N is the index of the image in the batch which makes up the frames. Or you can use `--batch-grid-size to write frames to a single animated output where the frames are all image grids produced from the images in the batch.

With larger --batch-size values, the use of --vae-slicing can make the difference between an out of memory condition and success, so it is recommended that you try this option if you experience an out of memory condition due to the use of --batch-size.

Image Processors

Images provided through --image-seeds can be processed before being used for image generation through the use of the arguments --seed-image-processors, --mask-image-processors, and --control-image-processors. In addition, dgenerates output can be post processed with the used of the --post-processors argument, which is useful for using the upscaler processor. An important note about --post-processors is that post processing occurs before any image grid rendering is preformed when --batch-grid-size is specified with a --batch-size greater than one, meaning that the output images are processed with your processor before being put into a grid.

Each of these options can receive one or more specifications for image processing actions, multiple processing actions will be chained together one after another.

Using the option --image-processor-help with no arguments will yield a list of available image processor names.

dgenerate --image-processor-help

# Output:
#
# Available image processors:
#
#     "sam"
#     "pidi"
#     "normal-bae"
#     "upscaler"
#     "grayscale"
#     "invert"
#     "posterize"
#     "mirror"
#     "flip"
#     "mlsd"
#     "leres"
#     "hed"
#     "solarize"
#     "midas"
#     "canny"
#     "lineart"
#     "openpose"
#     "lineart-anime"

Specifying one or more specific processors for example: --image-processor-help canny openpose will yield documentation pertaining to those processor modules. This includes accepted arguments and their types for the processor module and a description of what the module does.

Custom image processor modules can also be loaded through the --plugin-modules option as discussed in the Writing Plugins section.

All processors posses the arguments: output-file, output-overwrite, device, and model-offload

The output-file argument can be used to write the processed image to a specific file, if multiple processing steps occur such as when rendering an animation or multiple generation steps, a numbered suffix will be appended to this filename. Note that an output file will only be produced in the case that the processor actually modifies an input image in some way. This can be useful for debugging an image that is being fed into diffusion or a ControlNet.

The output-overwrite is a boolean argument can be used to tell the processor that you do not want numbered suffixes to be generated for output-file and to simply overwrite it.

The device argument can be used to override what device any hardware accelerated image processing occurs on if any. It defaults to the value of --device and has the same syntax for specifying device ordinals, for instance if you have multiple GPUs you may specify device=cuda:1 to run image processing on your second GPU, etc. Not all image processors respect this argument as some image processing is only ever CPU based.

The model-offload is a boolean argument that can be used to force any torch modules / tensors associated with an image processor to immediately evacuate the GPU or other non CPU processing device as soon as the processor finishes processing an image. Usually, any modules / tensors will be brought on to the desired device right before processing an image, and left on the device until the image processor object leaves scope and is garbage collected. This can be useful for achieving certain GPU or processing device memory constraints, however it is slower when processing multiple images in a row, as the modules / tensors must be brought on to the desired device repeatedly for each image. In the context of dgenerate invocations where processors can be used as preprocessors or postprocessors, the image processor object is garbage collected when the invocation completes, this is also true for the \image_process directive. Using this argument with a preprocess specification, such as --control-image-processors may yield a noticeable memory overhead reduction when using a single GPU, as any models from the image processor will be moved to the CPU immediately when it is done, clearing up VRAM space before the diffusion models enter GPU VRAM.

For an example, images can be processed with the canny edge detection algorithm or OpenPose (rigging generation) before being used for generation with a model + a ControlNet.

This image of a horse is used in the example below with a ControlNet that is trained to generate images from canny edge detected input.

# --control-image-processors is only used for control images
# in this case the single image seed is considered a control image
# because --control-nets is being used

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--variant fp16 --dtype float16 \
--vae "AutoencoderKL;model=madebyollin/sdxl-vae-fp16-fix" \
--sdxl-refiner stabilityai/stable-diffusion-xl-refiner-1.0 \
--inference-steps 30 \
--guidance-scales 8 \
--prompts "Majestic unicorn, high quality, masterpiece, high resolution; low quality, bad quality, sketches" \
--control-nets "diffusers/controlnet-canny-sdxl-1.0;scale=0.5" \
--image-seeds "horse.jpeg" \
--control-image-processors "canny;lower=50;upper=100" \
--gen-seeds 2 \
--output-size 1024 \
--output-path unicorn

The --control-image-processors has a special additional syntax that the other processor specification options do not, which is used to describe which processor group is affecting which control guidance image source in an --image-seeds specification.

For instance if you have multiple control guidance images, and multiple control nets which are going to use those images, or frames etc. and you want to process each guidance image with a separate processor OR processor chain. You can specify how each image is processed by delimiting the processor specification groups with + (the plus symbol)

Like this:

  • --control-nets "huggingface/controlnet1" "huggingface/controlnet2"

  • --image-seeds "image1.png, image2.png"

  • --control-image-processors "affect-image1" + "affect-image2"

Specifying a non-equal amount of control guidance images and --control-nets URIs is considered a syntax error and you will receive an error message if you do so.

You can use processor chaining as well:

  • --control-nets "huggingface/controlnet1" "huggingface/controlnet2"

  • --image-seeds "image1.png, image2.png"

  • --control-image-processors "affect-image1" "affect-image1-again" + "affect-image2"

In the case that you would only like the second image affected:

  • --control-nets "huggingface/controlnet1" "huggingface/controlnet2"

  • --image-seeds "image1.png, image2.png"

  • --control-image-processors + "affect-image2"

The plus symbol effectively creates a NULL processor as the first entry in the example above.

When multiple guidance images are present, it is a syntax error to specify more processor chains than control guidance images. Specifying less processor chains simply means that the trailing guidance images will not be processed, you can avoid processing leading guidance images with the mechanism described above.

This can be used with an arbitrary amount of control image sources and control nets, take for example the specification:

  • --control-nets "huggingface/controlnet1" "huggingface/controlnet2" "huggingface/controlnet3"

  • --image-seeds "image1.png, image2.png, image3.png"

  • --control-image-processors + + "affect-image3"

The two + (plus symbol) arguments indicate that the first two images mentioned in the control image specification in --image-seeds are not to be processed by any processor.

Upscaling with Diffusion Upscaler Models

Stable diffusion image upscaling models can be used via the model types torch-upscaler-x2 and torch-upscaler-x4.

The image used in the example below is this low resolution cat

# The image produced with this model will be
# two times the --output-size dimension IE: 512x512 in this case
# The image is being resized to 256x256, and then upscaled by 2x

dgenerate stabilityai/sd-x2-latent-upscaler --variant fp16 --dtype float16 \
--model-type torch-upscaler-x2 \
--prompts "a picture of a white cat" \
--image-seeds low_res_cat.png \
--output-size 256


# The image produced with this model will be
# four times the --output-size dimension IE: 1024x1024 in this case
# The image is being resized to 256x256, and then upscaled by 4x

dgenerate stabilityai/stable-diffusion-x4-upscaler --variant fp16 --dtype float16 \
 --model-type torch-upscaler-x4 \
--prompts "a picture of a white cat" \
--image-seeds low_res_cat.png \
--output-size 256 \
--upscaler-noise-levels 20

Sub Commands (image-process)

dgenerate implements additional functionality through the option --sub-command.

For a list of available sub-commands use --sub-command-help, which by default will list available sub-command names.

For additional information on a specific sub-command use --sub-command-help NAME multiple sub-command names can be specified here if desired however currently there is only one available.

All sub-commands respect the --plugin-modules and --verbose arguments even if their help output does not specify them, these arguments are handled by dgenerate and not the sub-command.

currently the only implemented sub-command is image-process, which you can read the help output of using dgenerate --sub-command image-process --help

The image-process sub-command can be used to run image processors implemented by dgenerate on any file of your choosing including animated images and videos.

It has a similar but slightly different design/usage to the main dgenerate command itself.

It can be used to run canny edge detection, openpose, etc. on any image or video/animated file that you want.

The help output of image-process is as follows:

usage: image-process [-h] [-p PROCESSORS [PROCESSORS ...]] [--plugin-modules PATH [PATH ...]]
                     [-o OUTPUT [OUTPUT ...]] [-ff FRAME_FORMAT] [-ox] [-r RESIZE] [-na] [-al ALIGN]
                     [-d DEVICE] [-fs FRAME_NUMBER] [-fe FRAME_NUMBER] [-nf | -naf]
                     input [input ...]

This command allows you to use dgenerate image processors directly on files of your choosing.

positional arguments:
  input                 Input file paths, may be a static images or animated files supported by
                        dgenerate. URLs will be downloaded.

options:
  -h, --help            show this help message and exit
  -p PROCESSORS [PROCESSORS ...], --processors PROCESSORS [PROCESSORS ...]
                        One or more image processor URIs, specifying multiple will chain them together.
  --plugin-modules PATH [PATH ...]
                        Specify one or more plugin module folder paths (folder containing __init__.py)
                        or python .py file paths to load as plugins. Plugin modules can implement image
                        processors.
  -o OUTPUT [OUTPUT ...], --output OUTPUT [OUTPUT ...]
                        Output files, parent directories mentioned in output paths will be created for
                        you if they do not exist. If you do not specify output files, the output file
                        will be placed next to the input file with the added suffix '_processed_N'
                        unless --output-overwrite is specified, in that case it will be overwritten. If
                        you specify multiple input files and output files, you must specify an output
                        file for every input file, or a directory (indicated with a trailing directory
                        seperator character, for example "my_dir/" or "my_dir"). Failure to specify an
                        output file with a URL as an input is considered an error. Supported file
                        extensions for image output are equal to those listed under --frame-format.
  -ff FRAME_FORMAT, --frame-format FRAME_FORMAT
                        Image format for animation frames. Must be one of: png, apng, blp, bmp, dib,
                        bufr, pcx, dds, ps, eps, gif, grib, h5, hdf, jp2, j2k, jpc, jpf, jpx, j2c,
                        icns, ico, im, jfif, jpe, jpg, jpeg, tif, tiff, mpo, msp, palm, pdf, pbm, pgm,
                        ppm, pnm, bw, rgb, rgba, sgi, tga, icb, vda, vst, webp, wmf, emf, or xbm.
  -ox, --output-overwrite
                        Indicate that it is okay to overwrite files, instead of appending a duplicate
                        suffix.
  -r RESIZE, --resize RESIZE
                        Preform naive image resizing (LANCZOS).

  -al ALIGN, --align ALIGN
                        Align images / videos to this value in pixels, default is 8. Specifying 1 will
                        disable resolution alignment.
  -d DEVICE, --device DEVICE
                        Processing device, for example "cuda", "cuda:1".
  -fs FRAME_NUMBER, --frame-start FRAME_NUMBER
                        Starting frame slice point for animated files (zero-indexed), the specified
                        frame will be included. (default: 0)

Overview of specifying image-process inputs and outputs

# Overview of specifying outputs, image-process can do simple operations
# like resizing images and forcing image alignment with --align, without the
# need to specify any other processing operations with --processors. Running
# image-process on an image with no other arguments simply aligns it to 8 pixels,
# given the defaults for its command line arguments

# More file formats than .png are supported for static image output, all
# extensions mentioned in the image-process --help documentation for --frame-format
# are supported, the supported formats are identical to that mentioned in the --image-format
# option help section of dgenerates --help output

# my_file.png -> my_file_processed_1.png

dgenerate --sub-command image-process my_file.png --resize 512x512

# my_file.png -> my_file.png (overwrite)

dgenerate --sub-command image-process my_file.png --resize 512x512 --output-overwrite

# my_file.png -> my_file.png (overwrite)

dgenerate --sub-command image-process my_file.png -o my_file.png --resize 512x512 --output-overwrite

# my_file.png -> my_dir/my_file_processed_1.png

dgenerate --sub-command image-process my_file.png -o my_dir/ --resize 512x512 --no-aspect

# my_file_1.png -> my_dir/my_file_1_processed_1.png
# my_file_2.png -> my_dir/my_file_2_processed_2.png

dgenerate --sub-command image-process my_file_1.png my_file_2.png -o my_dir/ --resize 512x512

# my_file_1.png -> my_dir_1/my_file_1_processed_1.png
# my_file_2.png -> my_dir_2/my_file_2_processed_2.png

dgenerate --sub-command image-process my_file_1.png my_file_2.png \
-o my_dir_1/ my_dir_2/ --resize 512x512

# my_file_1.png -> my_dir_1/renamed.png
# my_file_2.png -> my_dir_2/my_file_2_processed_2.png

dgenerate --sub-command image-process my_file_1.png my_file_2.png \
-o my_dir_1/renamed.png my_dir_2/ --resize 512x512

A few usage examples with processors:

# image-process can support any input format that dgenerate itself supports
# including videos and animated files. It also supports all output formats
# supported by dgenerate for writing videos/animated files, and images.

# create a video rigged with OpenPose, frames will be rendered to the directory "output" as well.

dgenerate --sub-command image-process my-video.mp4 \
-o output/rigged-video.mp4 --processors "openpose;include-hand=true;include-face=true"

# Canny edge detected video, also using processor chaining to mirror the frames
# before they are edge detected

dgenerate --sub-command image-process my-video.mp4 \
-o output/canny-video.mp4 --processors mirror "canny;blur=true;threshold-algo=otsu"

Upscaling with chaiNNer Compatible Upscaler Models

chaiNNer compatible upscaler models from https://openmodeldb.info/ and elsewhere can be utilized for tiled upscaling using dgenerates upscaler image processor and the --post-processors option. The upscaler image processor can also be used for processing input images via the other options mentioned in Image Processors such as --seed-image-processors

The upscaler image processor can make use of URLs or files on disk.

In this example we reference a link to the SwinIR x4 upscaler from the creators github release.

This uses the upscaler to upscale the output image by x4 producing an image that is 4096x4096

The upscaler image processor respects the --device option of dgenerate, and is CUDA accelerated by default.

dgenerate stabilityai/stable-diffusion-xl-base-1.0 --model-type torch-sdxl \
--variant fp16 --dtype float16 \
--sdxl-refiner stabilityai/stable-diffusion-xl-refiner-1.0 \
--sdxl-high-noise-fractions 0.8 \
--inference-steps 40 \
--guidance-scales 8 \
--output-size 1024 \
--prompts "Photo of a horse standing near the open door of a red barn, high resolution; artwork" \
--post-processors "upscaler;model=https://github.com/JingyunLiang/SwinIR/releases/download/v0.0/001_classicalSR_DIV2K_s48w8_SwinIR-M_x4.pth"

In addition to this the \image_process config directive, or --sub-command image-process can be used to upscale any file that you want including animated images and videos. It is worth noting that the sub-command and directive will work with any named image processor implemented by dgenerate.

# print the help output of the sub command "image-process"
# the image-process subcommand can process multiple files and do
# and several other things, it is worth reading :)

dgenerate --sub-command image-process --help

# any directory mentioned in the output spec is created automatically

dgenerate --sub-command image-process my-file.png \
--output output/my-file-upscaled.png \
--processors "upscaler;model=https://github.com/JingyunLiang/SwinIR/releases/download/v0.0/001_classicalSR_DIV2K_s48w8_SwinIR-M_x4.pth"

Writing and Running Configs

Program configuration can be read from STDIN and processed in batch with model caching, in order to increase speed when many invocations with different arguments are desired.

Loading the necessary libraries and bringing models into memory is quite slow, so using the program this way allows for multiple invocations using different arguments, without needing to load the libraries and models multiple times, only the first time, or in the case of models the first time the model is encountered.

When a model is loaded dgenerate caches it in memory with it’s creation parameters, which includes among other things the pipeline mode (basic, img2img, inpaint), user specified UNets, VAEs, LoRAs, Textual Inversions, and ControlNets. If another invocation of the model occurs with creation parameters that are identical, it will be loaded out of an in memory cache.

Diffusion Pipelines, user specified UNets, VAEs, and ControlNet models are cached individually.

UNets, VAEs and ControlNet model objects can be reused by diffusion pipelines in certain situations when specified explicitly and this is taken advantage of by using an in memory cache of these objects.

In effect, creation of a pipeline is memoized, as well as the creation of any pipeline subcomponents when you have specified them explicitly with a URI.

A number of things effect cache hit or miss upon a dgenerate invocation, extensive information regarding runtime caching behavior of a pipelines and other models can be observed using -v/--verbose

When loading multiple different models be aware that they will all be retained in memory for the duration of program execution, unless all models are flushed using the \clear_model_cache directive or individually using one of: \clear_pipeline_cache, \clear_unet_cache, \clear_vae_cache, or \clear_control_net_cache. dgenerate uses heuristics to clear the in memory cache automatically when needed, including a size estimation of models before they enter system memory, however by default it will use system memory very aggressively and it is not entirely impossible to run your system out of memory if you are not careful.

Environmental variables will be expanded in the provided input to STDIN when using this feature, you may use Unix style notation for environmental variables even on Windows.

There is also information about the previous file output of dgenerate that is available to use via Jinja2 templating which can be passed to --image-seeds, these include:

  • {{ last_images }} (An iterable of un-quoted filenames)

  • {{ last_animations }} (An iterable of un-quoted filenames)

There are templates for prompts, containing the previous prompt values:

  • {{ last_prompts }} (List of prompt objects with the un-quoted attributes ‘positive’ and ‘negative’)

  • {{ last_sdxl_second_prompts }}

  • {{ last_sdxl_refiner_prompts }}

  • {{ last_sdxl_refiner_second_prompts }}

A list of template variables with their types and values that are assigned by a dgenerate invocation can be printed out using the \templates_help directive mentioned in an example further down.

Available custom jinja2 functions/filters are:

  • {{ last(list_of_items) }} (Last element in a list)

  • {{ unquote('"unescape-me"') }} (shell unquote / split, works on strings and lists)

  • {{ quote('escape-me') }} (shell quote, works on strings and lists)

  • {{ format_prompt(prompt_object) }} (Format and quote one or more prompt objects with their delimiter, works on single prompts and lists)

The above can be used as either a function or filter IE: {{ "quote_me" | quote }}

Empty lines and comments starting with # will be ignored, comments that occur at the end of lines will also be ignored.

You can create a multiline continuation using \ to indicate that a line continues, if the next line starts with - it is considered part of a continuation as well even if \ had not been used previously. Comments cannot be interspersed with invocation or directive arguments without the use of \, at least on the last line before whitespace and comments start.

The following is a config file example that covers very basic syntax concepts:

#! dgenerate 3.4.1

# If a hash-bang version is provided in the format above
# a warning will be produced if the version you are running
# is not compatible (SemVer), this can be used anywhere in the
# config file, a line number will be mentioned in the warning when the
# version check fails

# Comments in the file will be ignored

# Each dgenerate invocation in the config begins with the path to a model,
# IE. the first argument when using dgenerate from the command line, the
# rest of the options that follow are the options to dgenerate that you
# would use on the command line

# Guarantee unique file names are generated under the output directory by specifying unique seeds

stabilityai/stable-diffusion-2-1 --prompts "an astronaut riding a horse" --seeds 41509644783027 --output-path output --inference-steps 30 --guidance-scales 10
stabilityai/stable-diffusion-2-1 --prompts "a cowboy riding a horse" --seeds 78553317097366 --output-path output --inference-steps 30 --guidance-scales 10
stabilityai/stable-diffusion-2-1 --prompts "a martian riding a horse" --seeds 22797399276707 --output-path output --inference-steps 30 --guidance-scales 10

# Guarantee that no file name collisions happen by specifying different output paths for each invocation

stabilityai/stable-diffusion-2-1 --prompts "an astronaut riding a horse" --output-path unique_output_1  --inference-steps 30 --guidance-scales 10
stabilityai/stable-diffusion-2-1 --prompts "a cowboy riding a horse" --output-path unique_output_2 --inference-steps 30 --guidance-scales 10

# Multiline continuations are possible implicitly for argument
# switches IE lines starting with '-'

stabilityai/stable-diffusion-2-1 --prompts "a martian riding a horse"
--output-path unique_output_3  # there can be comments at the end of lines
--inference-steps 30 \         # this comment is also ignored

# There can be comments or newlines within the continuation
# but you must provide \ on the previous line to indicate that
# it is going to happen

--guidance-scales 10

# The continuation ends (on the next line) when the last line does
# not end in \ or start with -

# the ability to use tail comments means that escaping of the # is sometimes
# necessary when you want it to appear literally, see: examples/config_syntax/tail-comments-config.txt
# for examples.


# Configuration directives provide extra functionality in a config, a directive
# invocation always starts with a backslash

# A clear model cache directive can be used inbetween invocations if cached models that
# are no longer needed in your generation pipeline start causing out of memory issues

\clear_model_cache

# Additionally these other directives exist to clear user loaded models
# out of dgenerates in memory cache individually

# Clear specifically diffusion pipelines

\clear_pipeline_cache

# Clear specifically user specified UNet models

\clear_unet_cache

# Clear specifically user specified VAE models

\clear_vae_cache

# Clear specifically ControlNet models

\clear_control_net_cache


# This model was used before but will have to be fully instantiated from scratch again
# after a cache flush which may take some time

stabilityai/stable-diffusion-2-1 --prompts "a martian riding a horse"
--output-path unique_output_4

To receive information about Jinja2 template variables that are set after a dgenerate invocation. You can use the \templates_help directive which is similar to the --templates-help option except it will print out all of the template variables assigned values instead of just their names and types. This is useful for figuring out the values of template variables set after a dgenerate invocation in a config file for debugging purposes. You can specify one or more template variable names as arguments to \templates_help to receive help for only the mentioned variable names.

Template variables set with the \set directive will also be mentioned in this output.

#! dgenerate 3.4.1

# Invocation will proceed as normal

stabilityai/stable-diffusion-2-1 --prompts "a man walking on the moon without a space suit"

# Print all set template variables

Here are examples of other available directives such as \set and \print as well as some basic Jinja2 templating usage. This example also covers the usage and purpose of \save_modules for saving and reusing pipeline modules such as VAEs etc. outside of relying on the caching system.

You can see all available config directives with the command dgenerate --directives-help, providing this option with a name, or multiple names such as: dgenerate --directives-help \save_modules \use_modules will print the documentation for the specified directives. The backslash may be omitted.

#! dgenerate 3.4.1

# You can define your own template variables with the \set directive
# the \set directive does not do any shell args parsing on its value
# operand, meaning the quotes will be in the string that is assigned
# to the variable my_prompt

\set my_prompt "an astronaut riding a horse; bad quality"

# If your variable is long you can use continuation, note that
# continuation replaces newlines and surrounding whitespace
# with a single space

\set my_prompt "my very very very very very very very \
                very very very very very very very very \
                long long long long long prompt"

# You can print to the console with templating using the \print directive
# for debugging purposes

\print {{ my_prompt }}


# the \gen_seeds directive can be used to store a list of
# random seed integers into a template variable.
# (they are strings for convenience)

\gen_seeds my_seeds 10

\print {{ my_seeds | join(' ') }}


# An invocation sets various template variables related to its
# execution once it is finished running

stabilityai/stable-diffusion-2-1 --prompts {{ my_prompt }} --gen-seeds 5


# Print a quoted filename of the last image produced by the last invocation
# This could potentially be passed to --image-seeds of the next invocation
# If you wanted to run another pass over the last image that was produced

\print {{ quote(last(last_images)) }}

# you can also get the first image easily with the function "first"

\print {{ quote(first(last_images)) }}


# if you want to append a mask image file name

\print "{{ last(last_images) }};my-mask.png"


# Print a list of properly quoted filenames produced by the last
# invocation separated by spaces if there is multiple, this could
# also be passed to --image-seeds

# in the case that you have generated an animated output with frame
# output enabled, this will contain paths to the frames

\print {{ quote(last_images) }}


# For loops are possible

\print {% for image in last_images %}{{ quote(image) }} {% endfor %}


# For loops are possible with normal continuation
# when not using a heredoc template continuation (mentioned below),
# such as when the loop occurs in the body of a directive or a
# dgenerate invocation, however this sort of continuation usage will
# replace newlines and whitespace with a single space.

# IE this template will be: "{% for image in last_images %} {{ quote(image) }} {% endfor %}"

\print {% for image in last_images %} \
        {{ quote(image) }} \
       {% endfor %}


# Access to the last prompt is available in a parsed representation
# via "last_prompt", which can be formatted properly for reuse
# by using the function "format_prompt"

stabilityai/stable-diffusion-2-1 --prompts {{ format_prompt(last(last_prompts)) }}

# You can get only the positive or negative part if you want via the "positive"
# and "negative" properties on a prompt object, these attributes are not
# quoted so you need to quote them one way or another, preferably using the
# dgenerate template function "quote" which will shell quote any special
# characters that the argument parser is not going to understand

stabilityai/stable-diffusion-2-1 --prompts {{ quote(last(last_prompts).positive) }}

# "last_prompts" returns all the prompts used in the last invocation as a list
# the "format_prompt" function can also work on a list

stabilityai/stable-diffusion-2-1 --prompts "prompt 1" "prompt 2" "prompt 3"

stabilityai/stable-diffusion-2-1 --prompts {{ format_prompt(last_prompts) }}


# Execute additional config with full templating.
# The sequence !END is interpreted as the end of a
# template continuation, a template continuation is
# started when a line begins with the character {
# and is effectively a heredoc, in that all whitespace
# within is preserved including newlines

{% for image in last_images %}
    stabilityai/stable-diffusion-2-1 --image-seeds {{ quote(image) }} --prompts {{ my_prompt }}
{% endfor %} !END


# Multiple lines can be used with a template continuation
# the inside of the template will be expanded to raw config
# and then be ran, so make sure to use line continuations within
# where they are necessary as you would do in the top level of
# a config file. The whole of the template continuation is
# processed by Jinja, from { to !END, so only one !END is
# ever necessary after the external template when dealing
# with nested templates

{% for image in last_images %}
    stabilityai/stable-diffusion-2-1
    --image-seeds {{ quote(image) }}
    --prompts {{ my_prompt }}
{% endfor %} !END


# The above are both basically equivalent to this

stabilityai/stable-diffusion-2-1 --image-seeds {{ quote(last_images) }} --prompts {{ my_prompt }}


# You can save modules from the main pipeline used in the last invocation
# for later reuse using the \save_modules directive, the first argument
# is a variable name and the rest of the arguments are diffusers pipeline
# module names to save to the variable name, this is an advanced usage
# and requires some understanding of the diffusers library to utilize correctly

stabilityai/stable-diffusion-2-1
--variant fp16
--dtype float16
--prompts "an astronaut walking on the moon"
--safety-checker
--output-size 512


\save_modules stage_1_modules feature_extractor safety_checker

# that saves the feature_extractor module object in the pipeline above,
# you can specify multiple module names to save if desired

# Possible Module Names:

# unet
# vae
# text_encoder
# text_encoder_2
# tokenizer
# tokenizer_2
# safety_checker
# feature_extractor
# controlnet
# scheduler


# To use the saved modules in the next invocation use  \use_modules

\use_modules stage_1_modules

# now the next invocation will use those modules instead of loading them from internal
# in memory cache, disk, or huggingface

stabilityai/stable-diffusion-x4-upscaler
--variant fp16
--dtype float16
--model-type torch-upscaler-x4
--prompts {{ format_prompt(last_prompts) }}
--image-seeds {{ quote(last_images) }}
--vae-tiling


# you should clear out the saved modules if you no longer need them
# and your config file is going to continue, or if the dgenerate
# process is going to be kept alive for some reason such as in
# some library usage scenarios, or perhaps if you are using it
# like a server that reads from stdin :)

\clear_modules stage_1_modules

The entirety of pythons builtin glob module is also accessible during templating, you can glob directories using functions from the glob module like so:

#! dgenerate 3.4.1

# The most basic usage is full expansion of every file

\set myfiles {{ quote(glob.glob('my_images/*.png')) }}

\print {{ myfiles }}

# If you have a LOT of files, you may want to
# process them using an iterator like so

{% for file in glob.iglob('my_images/*.png') %}
    \print {{ quote(file) }}
{% endfor %} !END

# Simple inline usage

stabilityai/stable-diffusion-2-1
--variant fp16
--dtype float16
--prompts "In the style of picaso"
--image-seeds {{ quote(glob.glob('my_images/*.png')) }}

The dgenerate sub-command image-process has a config directive implementation.

#! dgenerate 3.4.1

# print the help message of --sub-command image-process, this does
# not cause the config to exit

\image_process --help

\set myfiles {{ quote(glob.glob('my_images/*.png')) }}

# this will create the directory "upscaled"
# the files will be named "upscaled/FILENAME_processed_1.png" "upscaled/FILENAME_processed_2.png" ...

\image_process {{ myfiles }} \
--output upscaled/
--processors "upscaler;model=https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesr-general-x4v3.pth"


# the last_images template variable will be set, last_animations is also usable if
# animations were written. In the case that you have generated an animated output with frame
# output enabled, this will contain paths to the frames

\print {{ quote(last_images) }}

You can exit a config early if need be using the \exit directive

#! dgenerate 3.4.1

# exit the process with return code 1, which indicates an error

\print "some error occurred"
\exit 1

To utilize configuration files on Linux, pipe them into the command or use redirection:

# Pipe
cat my-config.txt | dgenerate

# Redirection
dgenerate < my-config.txt

On Windows CMD:

dgenerate < my-arguments.txt

On Windows Powershell:

Get-Content my-arguments.txt | dgenerate

Config Argument Injection

You can inject arguments into every dgenerate invocation of a batch processing configuration by simply specifying them. The arguments will added to the end of the argument specification of every call.

# Pipe
cat my-animations-config.txt | dgenerate --frame-start 0 --frame-end 10

# Redirection
dgenerate --frame-start 0 --frame-end 10 < my-animations-config.txt

On Windows CMD:

dgenerate  --frame-start 0 --frame-end 10 < my-animations-config.txt

On Windows Powershell:

Get-Content my-animations-config.txt | dgenerate --frame-start 0 --frame-end 10

If you need arguments injected from the command line within the config for some other purpose such as for using with the \image_process directive which does not automatically recieve injected arguments, use the injected_args and related injected_* template variables.

# all injected args

\print {{ quote(injected_args) }}

# just the injected device

\print {{ '--device '+injected_device if injected_device else '' }}

# was -v/--verbose injected?

\print {{ '-v' if injected_verbose else '' }}

# plugin module paths injected with --plugin-modules

\print {{ quote(injected_plugin_modules) if injected_plugin_modules else '' }}

Writing Plugins

dgenerate has the capability of loading in additional functionality through the use of the --plugin-modules option.

You simply specify one or more module directories on disk, or paths to python files, using this argument.

dgenerate supports implementing image processors and config directives through plugins.

A code example as well as a usage example for image processor plugins can be found in the “writing_plugins/image_processor” folder of the examples folder.

The source code for the built in canny processor, the openpose processor, and the simple pillow image operations processors can also be of reference as they are written as internal image processor plugins.

An example for writing config directives can be found in the “writing_plugins/config_directive” folder of the examples folder.

Currently the only internal directive that is implemented as a plugin is the \image_process directive, who’s source file can be located here, the source file for this directive is terse as most of \image_process is implemented as reusable code as mentioned below.

The behavior of \image_process which is also used for --sub-command image-process is is implemented here.

File Cache Control

dgenerate will cache --image-seeds files downloaded from the web while it is running in the directory ~/.cache/dgenerate/web, on Windows this equates to %HOME%\.cache\dgenerate\web

You can control where image seed files are cached with the environmental variable DGENERATE_WEB_CACHE.

This directory is automatically cleared when all instances of dgenerate have finished running.

If you start multiple dgenerate processes simultaneously they will share the cache while running in a manner that is multiprocess safe, the last running instance of dgenerate will clean out the cache.

Files downloaded from huggingface by the diffusers/huggingface_hub library will be cached under ~/.cache/huggingface/, on Windows this equates to %HOME%\.cache\huggingface\.

This is controlled by the environmental variable HF_HOME

In order to specify that all large model files be stored in another location, for example on another disk, simply set HF_HOME to a new path in your environment.

You can read more about environmental variables that affect huggingface libraries on this huggingface documentation page.
