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: WebDec 24, 2024 · Flipping: To flip image horizontally we need to reverse the order of columns of matrix which will result in changing the image horizontally.NumPy has method called fliplr() which return the array by reversing the order of columns.
