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 Example: Webnumpy.flip. #. Reverse the order of elements in an array along the given axis. The shape of the array is preserved, but the elements are reordered. New in version 1.12.0. Input array. Axis or axes along which to flip over.
