scikit-learn

scikit-learn is a Python module for machine learning built on top of SciPy and is distributed under the 3-Clause BSD license.

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 <https://scikit-learn.org/dev/about.html#authors>__ page for a list of core contributors.

It is currently maintained by a team of volunteers.

Installation

Dependencies


scikit-learn requires:

- Python (>= 3.6)
- NumPy (>= 1.13.3)
- SciPy (>= 0.19.1)
- joblib (>= 0.11)
- threadpoolctl (>= 2.0.0)

**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 plotting capabilities (i.e., functions start with ``plot_``
and classes end with "Display") require Matplotlib (>= 2.1.1). For running the
examples Matplotlib >= 2.1.1 is required. A few examples require
scikit-image >= 0.13, a few examples require pandas >= 0.18.0, some examples
require seaborn >= 0.9.0.

User installation

If you already have a working installation of numpy and scipy, the easiest way to install scikit-learn is using pip ::

pip install -U scikit-learn

or conda::

conda install scikit-learn

The documentation includes more detailed installation instructions <https://scikit-learn.org/stable/install.html>_.

Changelog

See the changelog <https://scikit-learn.org/dev/whats_new.html>__ for a history of notable changes to scikit-learn.

Development

We welcome new contributors of all experience levels. The scikit-learn community goals are to be helpful, welcoming, and effective. The Development Guide <https://scikit-learn.org/stable/developers/index.html>_ has detailed information about contributing code, documentation, tests, and more. We've included some basic information in this README.

Testing
~~~~~~~

After installation, you can launch the test suite from outside the
source directory (you will need to have ``pytest`` >= 3.3.0 installed)::

    pytest sklearn

See the web page https://scikit-learn.org/dev/developers/advanced_installation.html#testing
for more information.

    Random number generation can be controlled during testing by setting
    the ``SKLEARN_SEED`` environment variable.
