To use it, simply upload an image or use the example images below and click 'submit' to let the model predict the 5 most probable ImageNet classes. Results will show up in a few seconds. This is based on this space: This space is based on: https://huggingface.co/spaces/nielsr/perceiver-image-classification, image net labels are machine translated from english to spanish."
