| A CLIP (Contrastive Language-Image Pre-training) model trained on DFN-5B. |
| Data Filtering Networks (DFNs) are small networks used to automatically filter large pools of uncurated data. |
| This model was trained on 5B images that were filtered from a pool of 43B uncurated image-text pairs |
| (12.8B image-text pairs from CommonPool-12.8B + 30B additional public image-text pairs). |
|
|
| This model has been converted to PyTorch from the original JAX checkpoints from Axlearn (https://github.com/apple/axlearn). |
| 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/DFN5B-CLIP-ViT-H-14') |
| tokenizer = get_tokenizer('ViT-H-14') |
| |
| 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) |
