A CLIP (Contrastive Language-Image Pre-training) model trained on DFN-2B. |
|
Data Filtering Networks (DFNs) are small used to automatically filter large pools of uncurated data. |
|
This model was trained on 2B images that were filtered from a pool of 12.8B uncurated image-text pairs |
|
(12.8B image-text pairs from CommonPool-12.8B). |
|
|
|
These weights are directly usable in OpenCLIP (image + text). |

## Model Usage |
|
### With OpenCLIP |
|
``` |
|
import torch |
|
import torch.nn.functional as F |
|
from urllib.request import urlopen |
|
from PIL import Image |
|
from open_clip import create_model_from_pretrained, get_tokenizer |
|
|
|
model, preprocess = create_model_from_pretrained('hf-hub:apple/DFN2B-CLIP-ViT-B-16') |
|
tokenizer = get_tokenizer('ViT-B-16') |
|
|
|
image = Image.open(urlopen( |
|
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png' |
|
)) |
|
image = preprocess(image).unsqueeze(0) |
|
|
|
labels_list = ["a dog", "a cat", "a donut", "a beignet"] |
|
text = tokenizer(labels_list, context_length=model.context_length) |
|
|
|
with torch.no_grad(), torch.cuda.amp.autocast(): |
|
image_features = model.encode_image(image) |
|
text_features = model.encode_text(text) |
|
image_features = F.normalize(image_features, dim=-1) |
|
text_features = F.normalize(text_features, dim=-1) |
|
|
|
text_probs = torch.sigmoid(image_features @ text_features.T * model.logit_scale.exp() + model.logit_bias) |
|
|
|
zipped_list = list(zip(labels_list, [round(p.item(), 3) for p in text_probs[0]])) |
|
print("Label probabilities: ", zipped_list) |
|
