The project was started in 2007 by David Cournapeau as a Google Summer of Code project, and since then many volunteers have contributed. See the About us page for a list of core contributors.
Scikit-learn 0.20 was the last version to support Python 2.7 and Python 3.4. scikit-learn 0.23 and later require Python 3.6 or newer. scikit-learn 1.0 and later require Python 3.7 or newer.
Scikit-learn plotting capabilities (i.e., functions start with plot_ and classes end with “Display”) require Matplotlib (>= 2.2.2). For running the examples Matplotlib >= 2.2.2 is required. A few examples require scikit-image >= 0.14.5, a few examples require pandas >= 0.25.0, some examples require seaborn >= 0.9.0.
We welcome new contributors of all experience levels. The scikit-learn community goals are to be helpful, welcoming, and effective. The Development Guide has detailed information about contributing code, documentation, tests, and more. We’ve included some basic information in this README.
After installation, you can launch the test suite from outside the source directory (you will need to have pytest >= 5.0.1 installed):
