cpm

cpm is a fundamental package for Computational Psychiatry. It is designed to provide a set of tools for researchers and clinicians to analyze and model data in the field of Computational Psychiatry.

Installation and Usage

To install the package, run the following command:

pip install cpm-toolbox

Once the package is installed, you can import it in your Python code:

import cpm

Install from GitHub for Nightly Builds

In order to install the package from GitHub, run the following command:

pip install git+https://github.com/DevComPsy/cpm.git

Documentation

The documentation can be viewed here: link.

Citing cpm

If you are using cpm, we recommend citing the titular software paper (Dome et al., 2026):

@article{dome2026cpm,
  title = {cpm: {{A}} Python Library for Theory-Driven Modelling in Computational Psychiatry},
  author = {Dome, Lenard and Hezemans, Frank H. and Kadri, Kenza and Wagner, Ben J. and Webb, Andrew and Hauser, Tobias U.},
  year = 2026,
  journal = {PLOS Computational Biology},
  volume = {22},
  number = {7},
  pages = {1--31},
  publisher = {Public Library of Science},
  doi = {10.1371/journal.pcbi.1014481}
}

Development of documentation

The documentation is built with Sphinx from the docstrings in cpm/ and the pages in docs/. To build it locally, run the following commands in the root directory:

pip install -e ".[docs]"
python -m sphinx -b html docs docs/_build/html

Then open docs/_build/html/index.html in a browser. See CONTRIBUTING.md for how to write documentation and tutorials, and for a live preview while you write.

The documentation is published to GitHub Pages by the docs GitHub Actions workflow whenever main changes.

Development process

To work on the toolbox, create a new branch from the main branch. Then, create a pull request to merge the new feature into the main branch. Once the pull request is approved, merge the new feature into the main branch.

Branch naming convention

A git branch should start with a category. Pick one of these: feature, bugfix, hotfix, or test.

• feature is for adding, refactoring or removing a feature
• bugfix is for fixing a bug
• hotfix is for changing code with a temporary solution and/or without following the usual process (usually because of an emergency)
• test is for experimenting outside of an issue/ticket

See this link for some great description of the naming convention.

Commit message conventions

Please follow the Conventional Commits guidelines for commit messages. Feel free to use gitmoji for commit messages, but insert them at the end of the problem description. See this link for more information.

Pull request conventions

When creating a pull request, make sure to follow these conventions: link

Compiling the package

To compile the package, run the following command in the root directory:

python setup.py sdist bdist_wheel

Uploading the package to PyPi

To upload the package to PyPi, run the following command in the root directory:

twine upload dist/*

Development tools we use

• black linter for python code formatting
• numpy-style docstrings for documentation
• sphinx for documentation generation
• pytest for testing
