load_example

deepinv.utils.load_example(name, **kwargs)

Load example image from the DeepInverse HuggingFace using deepinv.utils.load_url_image() if image file or deepinv.utils.load_torch_url() if torch tensor in .pt file or deepinv.utils.load_np_url() if numpy array in npy or npz file.

Available examples for name include (see the HuggingFace repo for full list):

Parameters:

• name (str) – filename of the image from the HuggingFace dataset.

• kwargs (dict) – keyword args to pass to deepinv.utils.load_url_image()

Returns:

torch.Tensor containing the image.
