How to install PyTorch on Windows [Step-by-Step]

PyTorch is a popular machine learning library, easier to learn than other similar deep learning tools, according to specialists.

Before installing PyTorch, you must make sure you meet some prerequisites. Namely, to run Windows 7 or greater, Windows Server 2008 r2 or greater.

It is also recommended to have already installed the Anaconda auxiliary package for PyTorch 3.x (the only version compatible with Windows).
