Installation

The latest version is available to download via PyPI: pip install periodicity.

Alternatively, you can build the current development version from source by cloning this repo (git clone https://github.com/dioph/periodicity.git) and running pip install ./periodicity.

Development

If you're interested in contributing to periodicity, install pipenv and you can setup everything you need with pipenv install --dev.
