Install virtualenv with python3.7 -m pip install virtualenv (you may need a --user after install, it depends on your installation).
Create the virtual environment, for example virtualenv arasVenv.

Clone or download the repo and install the requirements with pip install -r requirements.txt.
Start a jupyter notebook with jupyter-notebook <name>.ipynb.
If you do not want the jupyter environment convert the notebook to a .py script with jupyter-nbconvert <name>.ipynb --to python.
You can also start an online interactive session with mybinder: there you just need to copy the URL of this github repo and you can launch the notebooks, once the container is ready. You have a shortcut here
