+#     In the example above, `RandomCrop` uses an external library's random number generator
 #     (in this case, Numpy's `np.random.int`). This can result in unexpected behavior with `DataLoader`

 #     In practice, it is safer to stick to PyTorch's random number generator, e.g. by using `torch.randint` instead.
