For other layouts shape is permuted accordingly. Outputs: out: 3D output tensor with shape (batch_size, channels, out_width) when layout is NCW. out_width is calculated as: To do that, we're going to define a variable torch_ex_float_tensor and use the PyTorch from NumPy functionality and pass in our variable numpy_ex_array. torch_ex_float_tensor = torch.from_numpy (numpy_ex_array) Then we can print our converted tensor and see that it is a PyTorch FloatTensor of size 2x3x4 which matches the NumPy multi-dimensional ...Apr 21, 2022 · A Computer Science portal for geeks.
