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.
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.
The documentation of PM4Py can be found at https://processintelligence.solutions/pm4py/.
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")PM4Py can be installed on Python 3.9.x / 3.10.x / 3.11.x / 3.12.x / 3.13.x / 3.14.x by invoking:
pip install -U pm4py
Optional features can be installed through extras. For example:
pip install -U "pm4py[polars,ml]"
Use pip install -U "pm4py[all]" to install every optional feature supported on the current platform.
For a reproducible installation using the exact dependency versions validated by the project, use:
pip install -U "pm4py[stable]"
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
The default installation contains the dependencies needed for mainstream usage. Additional integrations are grouped by
feature in pyproject.toml:
calendars: workalendarconnectors: requestsllm: openai and requestsml: pyemd and scikit-learnocel: jsonschema and pyarrowpolars: Polars dataframe supportsolvers: cvxoptstable: the exact dependency versions validated by the project and used by CIvisualization: pyviswindows: pygetwindow, pynput, and pywin32 (Windows only)
For a source checkout, install the project with python -m pip install -e .. Build, CI, and lint dependencies are
standard dependency groups and can be installed with, for example, python -m pip install --group lint.
To track the incremental updates, please refer to the CHANGELOG.md file.
