PyTorch in Action: A Step by Step Tutorial

Installation Guide

Step 1, donwload the Miniconda and installing it on your computer.

The reason why explain installing conda is that some of classmates don`t have a conda environment on their computer.

Step 2, create a conda virtual envriomment

In this ariticle, we assume that there is a CPU version of PyTorch is going to be installed. To specifically distinguish CPU version and GPU version, we`re going to create a virtual environment named "PyTorch-CPU".

In the Conda Prompt run the following commands:

conda create -n PyTorch-CPU pip

Step 3, install PyTorch

On the website of PyTorch(https://pytorch.org/), there is a guidance on the page. To chose the most appropriate options(e.g. as the follow figure).

In the Conda Prompt run the following commands:

activate PyTorh-CPU
conda install pytorch-cpu torchvision-cpu -c pytorch

Congratulations, installation of PyTorch is complete!
