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 page for a list of core contributors.
It is currently maintained by a team of volunteers.

Installation
Dependencies
scikit-learn requires:
- Python (>= 3.7)
- NumPy (>= 1.14.6)
- SciPy (>= 1.1.0)
- 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 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 (>= 2.2.3).
For running the examples Matplotlib >= 2.2.3 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.
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 -c conda-forge scikit-learn
The documentation includes more detailed installation instructions.
Changelog

Testing
After installation, you can launch the test suite from outside the source
directory (you will need to have pytest >= 5.0.1 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.
