Testing

After installation, you can launch the test form pgmpy source directory (you will need to have the pytest package installed):

$ pytest -v

to see the coverage of existing code use following command

$ pytest --cov-report html --cov=pgmpy

Documentation and usage

The documentation is hosted at: http://pgmpy.org/

We use sphinx to build the documentation. To build the documentation on your local system use:

$ cd /path/to/pgmpy/docs
$ make html

The generated docs will be in _build/html

Examples

We have a few example jupyter notebooks here: https://github.com/pgmpy/pgmpy/tree/dev/examples For more detailed jupyter notebooks and basic tutorials on Graphical Models check: https://github.com/pgmpy/pgmpy_notebook/
