clip-interrogator-sfw 0.6.1

Generate a prompt from an image (SFW version)

clip-interrogator-sfw

This is the SFW Version of the CLIP Interrogator by pharmapsychotic. I removed the NSFW words from flavors.txt by creating clip embeddings for obvious NSFW words and removing the top 20% similar words from flavors.txt resulting flavors-sfw.txt. I also removed some other words that I thought were not appropriate for a general audience. The first part of the interrogator is defined by the BLIB Model, so anything coming from the BLIB model is not modified.

Original README follows...

Want to figure out what a good prompt might be to create new images like an existing one? The CLIP Interrogator is here to get you answers!

Run it!

🆕 Now available as a Stable Diffusion Web UI Extension! 🆕

Run Version 2 on Colab, HuggingFace, and Replicate!

Version 1 still available in Colab for comparing different CLIP models

About

The CLIP Interrogator is a prompt engineering tool that combines OpenAI's CLIP and Salesforce's BLIP to optimize text prompts to match a given image. Use the resulting prompts with text-to-image models like Stable Diffusion on DreamStudio to create cool art!

Using as a library

Create and activate a Python virtual environment

python3 -m venv ci_env
(for linux  ) source ci_env/bin/activate
(for windows) .\ci_env\Scripts\activate

Install with PIP

# install torch with GPU support for example:
pip3 install torch torchvision --extra-index-url https://download.pytorch.org/whl/cu117

# install clip-interrogator
pip install clip-interrogator==0.5.4

# or for very latest WIP with BLIP2 support
#pip install clip-interrogator==0.6.0

You can then use it in your script

from PIL import Image
from clip_interrogator import Config, Interrogator
image = Image.open(image_path).convert('RGB')
ci = Interrogator(Config(clip_model_name="ViT-L-14/openai"))
print(ci.interrogate(image))

CLIP Interrogator uses OpenCLIP which supports many different pretrained CLIP models. For the best prompts for Stable Diffusion 1.X use ViT-L-14/openai for clip_model_name. For Stable Diffusion 2.0 use ViT-H-14/laion2b_s32b_b79k

Configuration

The Config object lets you configure CLIP Interrogator's processing.

• clip_model_name: which of the OpenCLIP pretrained CLIP models to use
• cache_path: path where to save precomputed text embeddings
• download_cache: when True will download the precomputed embeddings from huggingface
• chunk_size: batch size for CLIP, use smaller for lower VRAM
• quiet: when True no progress bars or text output will be displayed

On systems with low VRAM you can call config.apply_low_vram_defaults() to reduce the amount of VRAM needed (at the cost of some speed and quality). The default settings use about 6.3GB of VRAM and the low VRAM settings use about 2.7GB.

See the run_cli.py and run_gradio.py for more examples on using Config and Interrogator classes.

Ranking against your own list of terms (requires version 0.6.0)

from clip_interrogator import Config, Interrogator, LabelTable, load_list
from PIL import Image

ci = Interrogator(Config(blip_model_type=None))
image = Image.open(image_path).convert('RGB')
table = LabelTable(load_list('terms.txt'), 'terms', ci)
best_match = table.rank(ci.image_to_features(image), top_count=1)[0]
print(best_match)
