This project is a playground for my first tests with Pytorch. Its purpose is mainly to provide a setup doc and sample code for myself.

As Platform Win10 is used

Guide: https://pytorch.org/get-started/locally/

Package Manager: https://chocolatey.org/

I'm not sure if this is necessary because conda also installs its own python.

choco install python

Command line package and environment manager

1. Install Conda

   choco install anaconda3
   

2. Get a conda prompt

   In C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit) are the shortcuts to the conda prompts

   %windir%\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy ByPass -NoExit -Command "& 'C:\tools\Anaconda3\shell\condabin\conda-hook.ps1' ; conda activate 'C:\tools\Anaconda3' "
   %windir%\System32\cmd.exe "/K" C:\tools\Anaconda3\Scripts\activate.bat C:\tools\Anaconda3
   

   In the conda prompt you can use all commands to configure your enviroment. https://conda.io/projects/conda/en/latest/user-guide/cheatsheet.html

3. Create an enviroment for pytorch

   conda info
   conda create --name pytorch python=3.8
   conda activate pytorch
   conda install pytorch torchvision cpuonly -c pytorch
   

   Use https://pytorch.org/get-started/locally/ to generate your script

4. Test installation

   Open python console for the environment C:\tools\Anaconda3\python.exe

   from __future__ import print_function
   import torch
   x = torch.rand(5, 3)
   print(x) 
   

   import torch
   torch.cuda.is_available()
