Run setup_environment.py when you clone the repository.
This will install a virtual python environment
in the main project directory. It will then install the external dependencies into this environment from PyPI using
pip. (This will NOT install any non-python dependencies such as MongoDB, as the process for that depends on your
distribution. You will have to do that manually).
When testing from the command line, remember to activate the virtual environment (source .venv/bin/activate on
bash/zsh). Instructions for other shells, along with more in-depth information about Python virtual environments, can be
found here.
