Dependencies

PyCS3 is developed using python 3.7 and might be fine with older versions.

It requires numpy, scipy, matplotlib and multiprocess. Those are all you need to run the free-knot splines.

The regression difference technique have further dependencies:

scikit-learn

Download

Get the latest PyCS by cloning it from GitLab:

git clone https://gitlab.com/cosmograil/PyCS3

Installation

If you want to update or tweak the sources, we suggest to just add your cloned repository to your PYTHONPATH or type :

python setup.py develop

If you don’t plan to tweak the code, you can also simply

python setup.py install

or maybe

python setup.py install --user

… if you don’t have write access to the global site-packages directory of your machine.

Tests

PyCS3 now have automatic tests to verify that everything works correctly. If you want to check your installation, you will first need to install PyTest with the command :

pip install pytest --user

Then, you can simply go in the PyCS3 repository and run the command :

pytest

Running all the tests should take between 5 and 10 minutes.
