💻 Quick Start

import torch
import timm

# Load the model directly from the Hub
model = timm.create_model(
    'hf-hub:parlange/deit3-gravit-c3',
    pretrained=True
)
model.eval()

# Example inference
dummy_input = torch.randn(1, 3, 224, 224)
with torch.no_grad():
    output = model(dummy_input)
    predictions = torch.softmax(output, dim=1)
print(f"Lens probability: {predictions[0][1]:.4f}")
