In this article, we are going to see how you can install PyTorch in the Linux system. We are using Ubuntu 20 LTS you can use any other one. To successfully install PyTorch in your Linux system, follow the below procedure:

First, check if you are using python’s latest version or not.

Because PyGame requires python 3.7 or a higher version, make sure you are using the latest version of python. Type the below command to check the version of python.

pip3 install torch==1.8.1+cpu torchvision==0.9.1+cpu torchaudio==0.8.1 -f https://download.pytorch.org/whl/torch_stable.html

The above command was used to install PyTorch in the system that didn't have GPU. You just copy the command and paste it into the terminal and run it.
