Python examples

from all_clip import load_clip

from PIL import Image
import pathlib


model, preprocess, tokenizer = load_clip("open_clip:ViT-B-32/laion2b_s34b_b79k", device="cpu", use_jit=False)


image = preprocess(Image.open(str(pathlib.Path(__file__).parent.resolve()) + "/CLIP.png")).unsqueeze(0)
text = tokenizer(["a diagram", "a dog", "a cat"])

with torch.no_grad(), torch.cuda.amp.autocast():
    image_features = model.encode_image(image)
    text_features = model.encode_text(text)
    image_features /= image_features.norm(dim=-1, keepdim=True)
    text_features /= text_features.norm(dim=-1, keepdim=True)

    text_probs = (100.0 * image_features @ text_features.T).softmax(dim=-1)

print("Label probs:", text_probs)  # prints: [[1., 0., 0.]]

API

This module exposes a single function load_clip:

• clip_model CLIP model to load (default ViT-B/32). Specify it as "open_clip:ViT-B-32/laion2b_s34b_b79k" to use the open_clip or "hf_clip:patrickjohncyh/fashion-clip" to use the hugging face clip model.
• use_jit uses jit for the clip model (default True)
• warmup_batch_size warmup batch size (default 1)
• clip_cache_path cache path for clip (default None)
• device device (default None)

Related projects

• clip-retrieval to use clip for inference, and retrieval
• open_clip to train clip models
• CLIP_benchmark to evaluate clip models

Supported models

OpenAI

Specify the model as "ViT-B-32"

Openclip

"open_clip:ViT-B-32/laion2b_s34b_b79k" to use the open_clip

HF CLIP

"hf_clip:patrickjohncyh/fashion-clip" to use the hugging face

Deepsparse backend

DeepSparse is an inference runtime for fast sparse model inference on CPUs. There is a backend available within clip-retrieval by installing it with pip install deepsparse-nightly[clip], and specifying a clip_model with a prepended "nm:", such as "nm:neuralmagic/CLIP-ViT-B-32-256x256-DataComp-s34B-b86K-quant-ds" or "nm:mgoin/CLIP-ViT-B-32-laion2b_s34b_b79k-ds".

For development

Either locally, or in gitpod (do export PIP_USER=false there)

Setup a virtualenv:

python3 -m venv .env
source .env/bin/activate
pip install -e .

to run tests:

pip install -r requirements-test.txt

then

make lint
make test

You can use make black to reformat the code

python -m pytest -x -s -v tests -k "dummy" to run a specific test
