After downloading the code repository (via git clone), change to the repository directory (cd neural_prophet), activate your virtual environment, and install neuralprophet as python package with
pip install -e .[dev]
(Including the optional -e flag will install neuralprophet in "editable" mode, meaning that instead of copying the files into your virtual environment, a symlink will be created to the files where they are.)
Additionally you must run $ neuralprophet_dev_setup in your console to run the dev-setup script which installs appropriate git hooks for testing etc.
As far as possible, we follow the Google Python Style Guide
