For example, if you have a 2-D or 3-D grid where you need to perform (elementwise) operations, Pytorch-CUDA can be hundeds of times faster than Numpy, or even compiled C/FORTRAN code. I have tested this dozens of times during my PhD. – C-3PO.

Cupy vs Pytorch: Which is better for deep learning?

WebJan 28, 2024 · The recommended way to build tensors in Pytorch is to use the following two factory functions: torch.tensor and torch.as_tensor. torch.tensor always copies the data.
