Impossible to install Pytorch==0.3.1 for ubuntu 22.04 (install old script dependancies)

I am struggling like hell to make old python scripts work, and it is driving me crazy.

I truly thought scripts from 4 years ago wouldn’t be so hard to run today…

So I am trying to run this project : https://github.com/jthsieh/DDPAE-video-prediction

For which there are these recommendations :
All code was developed and tested on Python 3.6, PyTorch 0.3.1, and Pyro 0.2.
To view results, you need to install tensorflow and tensorbaordX.

So first things first, I installed python3.6, which already is a little tricky.

But module PyTorch0.3.1 does not exist and it seems really difficult to find out.

I don’t understand why there isn’t a way to go back in time with python in a virtual machin.

Is here a simple way to do this ?

Do I have to do all dependencies, roll back and everything by hand ?

Please folks, I am so tired of trying to make old scientific projects work….

I tried to download the package from Pytorch website, but didn’t find any Linux version…
I tried to use the pip version in the python 3.6 folder, and surprisingly it didn’t change the output of
pip install torch==0.3.1 or pip install pytorch==0.3.1
