WebUse the .view () method to reshape a tensor. This method receives heavy use, because many neural network components expect their inputs to have a certain shape. Often you will need to reshape before passing your data to the component. x = torch.randn(2, 3, 4) print(x) print(x.view(2, 12)) # Reshape to 2 rows, 12 columns # Same as above. WebNov 1, 2024 · Creating Tensor in PyTorch There are various methods to create a tensor in PyTorch. A tensor can contain elements of a single data type. We can create a tensor using a python list or NumPy array. The torch has 10 variants of tensors for both GPU and CPU.
