Support#

There are several channels to connect with scikit-learn developers for assistance, feedback, or contributions.

Note: Communications on all channels should respect our Code of Conduct.

Mailing Lists#

Main Mailing List: Join the primary discussion platform for scikit-learn at scikit-learn Mailing List.
Commit Updates: Stay informed about repository updates and test failures on the scikit-learn-commits list.

User Questions#

If you have questions, this is our general workflow.

Stack Overflow: Some scikit-learn developers support users using the [scikit-learn] tag.
General Machine Learning Queries: For broader machine learning discussions, visit Stack Exchange.

When posting questions:

Please use a descriptive question in the title field (e.g. no “Please help with scikit-learn!” as this is not a question)
Provide detailed context, expected results, and actual observations.
Include code and data snippets (preferably minimalistic scripts, up to ~20 lines).
Describe your data and preprocessing steps, including sample size, feature types (categorical or numerical), and the target for supervised learning tasks (classification type or regression).

Note: Avoid asking user questions on the bug tracker to keep the focus on development.

GitHub Discussions Usage questions such as methodological
Stack Overflow Programming/user questions with [scikit-learn] tag
GitHub Bug Tracker Bug reports - Please do not ask usage questions on the issue tracker.
Discord Server Current pull requests - Post any specific PR-related questions on your PR, and you can share a link to your PR on this server.

Bug Tracker#

Encountered a bug? Report it on our issue tracker

Include in your report:

Steps or scripts to reproduce the bug.
Expected and observed outcomes.
Python or gdb tracebacks, if applicable.
The ideal bug report contains a short reproducible code snippet, this way anyone can try to reproduce the bug easily.
If your snippet is longer than around 50 lines, please link to a gist or a github repo.

Tip: Gists are Git repositories; you can push data files to them using Git.
