Vit H 14 CLIPA Datacomp1b

🚀 Model card for ViT-H-14-CLIPA-datacomp1B

A CLIPA-v2 model for zero-shot image classification, leveraging contrastive image-text learning.

🚀 Quick Start

The ViT-H-14-CLIPA-datacomp1B is a powerful model for zero-shot image classification. It can classify images into various categories without explicit training on those categories.

✨ Features

• Contrastive Image-Text Learning: Enables effective zero-shot image classification.
• Zero-Shot Capability: Can classify images into unseen categories.

📦 Installation

The model can be used with the open_clip library. You can install it using the following command (assuming you have Python and pip installed):

pip install open_clip

💻 Usage Examples

Basic Usage

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:ViT-H-14-CLIPA')
tokenizer = get_tokenizer('hf-hub:ViT-H-14-CLIPA')

image = Image.open(urlopen(
    'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
))
image = preprocess(image).unsqueeze(0)

text = tokenizer(["a diagram", "a dog", "a cat", "a beignet"], 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 = (100.0 * image_features @ text_features.T).softmax(dim=-1)

print("Label probs:", text_probs)  # prints: [[0., 0., 0., 1.0]]
