Daft is a Python package that uses matplotlib to render pixel-perfect probabilistic graphical models for publication in a journal or on the internet. With a short Python script and an intuitive model-building syntax you can design directed (Bayesian Networks, directed acyclic graphs) and undirected (Markov random fields) models and save them in any formats that matplotlib supports (including PDF, PNG, EPS and SVG).


Installing the most recent stable version of Daft should be pretty easy if you use pip:

python -m pip install daft

Otherwise, you can download the source and run:

python -m pip install -e .

in the root directory.

Daft only depends on matplotlib and numpy. These are standard components of the scientific Python stack but if you don’t already have them installed pip will try to install them for you.


If you have any problems or questions, open an “issue” on Github.
