Webnumpy.fliplr(m) [source] # Reverse the order of elements along axis 1 (left/right). For a 2-D array, this flips the entries in each row in the left/right direction. Columns are preserved, but appear in a different order than before. Parameters: marray_like Input array, must be at least 2-D. Returns: fndarray A view of m with the columns reversed. 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: irish burn roller
