Model Usage

With OpenCLIP

Note: Due to differences in the default epsilon values for LayerNorm initialization between JAX and PyTorch, we made some modifications in open_clip/transformer.py to align the model's behavior. Refer to https://github.com/UCSC-VLAA/CLIPS for more details.

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

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