when copying modules/tensors around, which one should I use? are they interchangable? Thanks a lot

When you use .data, you get a new Tensor with requires_grad=False, so cloning it won’t involve autograd. So both are equivalent, but there might be a (small) speed difference, I am not sure about that. Another use case could is when you want to clone/copy a non-parameter Tensor without autograd. Yo…
