Question about the choice of `contiguous` usage

[shabie]

Hi,

Thanks a lot for putting this implementation out there. It helped me a lot!

I was just curious why the contiguous() was called after permute or transpose but always before view. Would it be bad to call it after view?

Here is an example:

https://github.com/evelinehong/Transformer_Relative_Position_PyTorch/blob/fd1163eb72d74538932f4f2d62e9c2e876f232e5/relative_position.py#L79

I believe certain operations like view does not behave as it should if the tensor is not contiguous, therefore the contigious() call.
