PM4Py

PM4Py is a python library that supports state-of-the-art process mining algorithms in Python. It is open source and intended to be used in both academia and industry projects.

PM4Py is managed and developed by PIS — Process Intelligence Solutions (https://processintelligence.solutions/), a spin-off from the Fraunhofer Institute for Applied Information Technology FIT where PM4Py was initially developed.

Licensing

The open-source version of PM4Py, available on GitHub (https://github.com/process-intelligence-solutions/pm4py), is licensed under the GNU Affero General Public License version 3 (AGPL-3.0).

We offer a separate version of PM4Py for commercial use in closed-source environments under a different license. For more information about the licensing options for using PM4Py in closed-source settings, please visit https://processintelligence.solutions/pm4py#licensing.

Documentation / API

First Example

Here is a simple example to spark your interest:

import pm4py

if __name__ == "__main__":
    log = pm4py.read_xes('<path-to-xes-log-file.xes>')
    net, initial_marking, final_marking = pm4py.discover_petri_net_inductive(log)
    pm4py.view_petri_net(net, initial_marking, final_marking, format="svg")

Installation

PM4Py can be installed on Python 3.9.x / 3.10.x / 3.11.x / 3.12.x / 3.13.x by invoking:

pip install -U pm4py

PM4Py is also running on older Python environments with different requirements sets, including:

• Python 3.8 (3.8.10): third_party/old_python_deps/requirements_py38.txt

Requirements

PM4Py depends on some other Python packages, with different levels of importance:

• Essential requirements: numpy, pandas, deprecation, networkx
• Normal requirements (installed by default with the PM4Py package, important for mainstream usage): graphviz, intervaltree, lxml, matplotlib, pydotplus, pytz, scipy, tqdm
• Optional requirements (not installed by default): requests, pyvis, jsonschema, workalendar, pyarrow, scikit-learn, polars, openai, pyemd, pyaudio, pydub, pygame, pywin32, pygetwindow, pynput

Release Notes

To track the incremental updates, please refer to the CHANGELOG.md file.

Third Party Dependencies

As scientific library in the Python ecosystem, we rely on external libraries to offer our features. In the /third_party folder, we list all the licenses of our direct dependencies. Please check the /third_party/LICENSES_TRANSITIVE file to get a full list of all transitive dependencies and the corresponding license.
