Torch flip and torch split

Webtorch.flip makes a copy of input ’s data. This is different from NumPy’s np.flip , which returns a view in constant time. Since copying a tensor’s data is more work than viewing that data, torch.flip is expected to be slower than np.flip. Parameters: input ( Tensor) – the input tensor. dims ( a list or tuple) – axis to flip on.
