If you didn't have python installed already you can follow this link.
To run the python script in the a docker environment you obviously need to install docker, here.
If you're using Fedora 31, I recommend you to follow this blog for the installation. This blog helpes you to fix the cgroup issue on Fedora 31 with docker at the same time.
Simple use the script in a terminal where you have cloned this repository run_docker.sh .
If you're on Windows, just copy-paste the docker command line in the script to your terminal. Otherwise you can still run it whitout docker.
Simple open a terminal, go to the directory where you clone this repo and run ./main.py
On Windows, it might be python ./main.py .
