Installation

There are some python libraries that are necesary for this project. I recommend creating a virtual enviroment to have all of those libraries isolated from your system packages.

You can install them using the requirements.txt or just with pip install <library>. I've tested both methods and both works, in case any library is updated and gives any problem, the requirements.txt should still work.

requirements.txt method

cd /path/to/project
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
deactivate

pip install <library> method

cd /path/to/project
python -m venv .venv
source .venv/bin/activate
pip install --upgrade pip
