transforms. The input of randomcrop() can only be PIL image, not tensor

This is the original code

Report errors ：TypeError: ‘builtin_function_or_method’ object is not iterable

This is the changed code

Report errors ：TypeError: img should be PIL Image. Got <class ‘torch.Tensor’>

So I type in tensor It is not right , You should enter PIL image

However, I read a lot of information on the Internet that this function is correct tensor and PIL Fine , I don 't know which one is right , I think I can only input PIL image It can't be tensor

I replace the input with data_i_pil = transforms.ToPILImage()(data_i) After that, the program can run normally

Many people on the Internet say that this function is right tensor and PIL Fine , It's not , Let me give you an example , The following link is one of them
