degirum-cli 0.1.0

Degirum AI package with CLI for image and video prediction

Degirum CLI

Degirum CLI is a command-line tool for running AI inference on images, videos, and benchmarking AI models using the Degirum PySDK. The CLI provides default configurations for quick use, while allowing you to customize your commands by providing your own arguments.

Features

• Run AI inference on images and videos: Use pre-trained models from Degirum's model zoo for object detection, face recognition, and more.
• Benchmark multiple models: Evaluate the performance of AI models by measuring FPS and efficiency across different configurations.
• Flexible configuration: Run commands with sensible defaults, or override options via the command line or a configuration file.
• Support for extra options: Pass additional keyword arguments to the inference engine, such as measure_time=True, directly from the CLI.

Installation

1. Clone the repository:

   git clone https://github.com/DeGirum/degirum_cli.git
   cd <your-repo-directory>
   

2. Install the required dependencies:

   pip install -r requirements.txt
   

3. Install the package locally:

   pip install .
   

Usage

Setting the DEGIRUM_CLOUD_TOKEN Environment Variable

To access hardware options and model zoos in the DeGirum Cloud Platform with degirum_cli, you need to pass the DEGIRUM_CLOUD_TOKEN variable to the functions. The token can be set as an environment variable instead of passing it as an argument to every function. For detailed instructions on how to set this environment variable across various systems (including Linux, macOS, Windows, and virtual environments), please refer to this guide. Rest of the user guide below assumes that the token is set as an environment variable. If you prefer not to set it, remember to pass it as an argument (--token) to the various command line utilities described below.

Running with Defaults

The Degirum CLI comes with default values for most options, allowing you to run commands immediately without specifying arguments.

1. Image Inference (with defaults)

   • You can run AI inference on a default image with a pre-configured model:

     degirum_cli predict-image
     

   • This will use the following defaults:
     • Inference Host: @cloud
     • Model Zoo: degirum/public
     • Model: yolov8n_relu6_coco--640x640_quant_n2x_orca1_1
     • Image Source: A built-in example image.

2. Video Inference (with defaults)

   • You can run AI inference on a default video with a pre-configured model:

     degirum_cli predict-video
     

3. Benchmarking (with defaults)

   • Run the benchmark command with default settings:

     degirum_cli benchmark
     

   • This will benchmark multiple default models and use the cloud for inference.

Using the Help Command

The Degirum CLI provides built-in help for all commands, making it easy to see the available options, their descriptions, and the default values. Use the --help flag to display the full details of any command.

For example:

1. Help for predict-image Command:

   degirum_cli predict-image --help
   

   This will show the following information:

   Usage: degirum_cli predict-image [OPTIONS] [EXTRA_ARGS]...
   
   Run AI inference on an image with extra options.
   
   Options:
     --inference-host-address TEXT  Hardware location for inference (e.g.,
                                    @cloud, @local, IP).  [default: @cloud]
     --model-zoo-url TEXT           URL or path to the model zoo.  [default:
                                    degirum/public]
     --model-name TEXT              Name of the model to use for inference.
                                    [default: yolov8n_relu6_coco--640x640_quant_n2x_orca1_1]
     --image-source TEXT            Path or URL to the image for inference.
                                    [default: https://raw.githubusercontent.com/DeGirum/PySDKExamples/main/images/ThreePersons.jpg]
     --token TEXT                   Cloud platform token to use for inference.
                                    Attempts to load from environment if not provided.
     --help                         Show this message and exit.
   

   This output provides the default values for each argument and explains the usage of the command.

2. Help for Other Commands:

   • You can also run the --help flag with other commands like predict-video or benchmark to see the specific options available for each.

   degirum_cli predict-video --help
   degirum_cli benchmark --help
   

This feature makes it easy to explore the available options and use the CLI effectively.

Customizing the Command

Once you're familiar with the defaults, you can override the parameters to fit your needs by passing arguments.

1. Image Inference with Custom Arguments

   • Example of customizing image inference:

     degirum_cli predict-image --inference-host-address @cloud --model-zoo-url degirum/public --model-name yolov8n_relu6_coco--640x640_quant_n2x_orca1_1 --image-source /path/to/image.jpg
     

   • You can also pass extra arguments as key-value pairs:

     degirum_cli predict-image --inference-host-address @cloud --model-zoo-url degirum/public --model-name yolov8n_relu6_coco--640x640_quant_n2x_orca1_1 --image-source /path/to/image.jpg measure_time=True
     

2. Video Inference with Custom Arguments

   • Example of running inference on a video with custom arguments:

     degirum_cli predict-video --inference-host-address @cloud --model-zoo-url degirum/public --model-name yolov8n_relu6_coco--640x640_quant_n2x_orca1_1 --video-source /path/to/video.mp4
     

3. Benchmarking with Custom Configurations

   • Example of customizing the benchmark command:

     degirum_cli benchmark --config-file /path/to/config.yaml --iterations 200 --token your_token measure_time=True
     

   • If no configuration file is provided, default model zoo and models are used:

     degirum_cli benchmark --iterations 100 --token your_token
     

   • Example configuration file (config.yaml):

     model_zoo_url: degirum/public
     model_names:
       - mobilenet_v1_imagenet--224x224_quant_n2x_orca1_1
       - yolov8n_relu6_coco--640x640_quant_n2x_orca1_1
     

Command-Line Options

• --inference-host-address: Specify where to run inference, such as @cloud for cloud servers or IP addresses for local servers.
• --model-zoo-url: URL or path to the model zoo for loading pre-trained models.
• --model-name: Specify the name of the model to use for inference.
• --image-source / --video-source: Path to the image or video file to be used for inference.
• --iterations: Number of iterations for benchmarking.
• --token: Provide your Degirum cloud platform token.
• Additional arguments: Pass additional options (e.g., measure_time=True) for fine-tuning the inference process.
