Scikit-learn

Overview

This skill provides comprehensive guidance for machine learning tasks using scikit-learn, the industry-standard Python library for classical machine learning. Use this skill for classification, regression, clustering, dimensionality reduction, preprocessing, model evaluation, and building production-ready ML pipelines.

Installation

Targets scikit-learn 1.9.1, verified with Python 3.13. The release requires Python 3.11+; use its published wheels for your interpreter/platform. See the 1.9 release notes. The bundled scripts and regression tests are executable examples. Reference snippets using caller-provided X, y, columns, or placeholders are illustrative adaptations, not complete standalone programs.

Install the PyPI package scikit-learn (not the deprecated sklearn package on PyPI). Import in code as sklearn.

# Install scikit-learn using uv
uv pip install "scikit-learn==1.9.1"

# Optional: plotting utilities and bundled script dependencies
uv pip install "scikit-learn[plots]==1.9.1" matplotlib pandas
