The following steps covers the setup process
You also should use virtualenv to build/develop the project and I recommend the use of pyenv with pyenv-virtualenv to manage multiple python environments.
pyenv install 3.7.6
pyenv virtualenv 3.7.6 PINP
pyenv activate PINP
If you have any problems installing pyenv try these common solutions.
Open your bash and run the follow command to install all the project dependencies, you just need to run the command one time
(PINP) $ python -m pip install -r requirements.txt
