Install (w/ GPU) #

win10 #

Install NV GPU driver and compatible CUDA version first, or install using pip together.
See PyTorch doc’s selector to find a compatible CUDA version.
pytorch-with-cuda
Then use the cmd given by the selector to install PyTorch:

pip source: # 

pip install pytorch torchvision torchaudio cudatoolkit=11.1

pip binary: # 

pip3 install torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio===0.9.0 -f https://download.pytorch.org/whl/torch_stable.html

Tip: the torch...whl file is > 3GB, which can be pre-downloaded via IDM etc., then:

pip3 install torch-1.9.0+cu111-cp39-cp39-win_amd64.whl torchvision==0.10.0+cu111 torchaudio===0.9.0 -f https://download.pytorch.org/whl/torch_stable.html

conda: # 

conda install pytorch torchvision torchaudio cudatoolkit=11.1

verify installation # 

import torch
torch.cuda.is_available()

Install Libs with GPU/Cuda Support (e.g. GNN Libs) #

Tip: Compatible versions of GPU/Cuda and torch should be installed before the following cmds. (Those cmds can also be run within Pycharm’s venv “Terminal” in its UI to install into the venv.)
