Support

There are several ways to get in touch with the developers.

Mailing List

User questions

  • Some scikit-learn developers support users on StackOverflow using the [scikit-learn] tag.
  • For general theoretical or methodological Machine Learning questions metaoptimize.com/qa is probably a more suitable venue.

In both cases please use a descriptive question in the title field (e.g. no “Please help with scikit-learn!” as this is not a question) and put details on what you tried to achieve, what were the expected results and what you observed instead in the details field.

Code and data snippets are welcome. Minimalistic (up to ~20 lines long) reproduction script very helpful.

Please describe the nature of your data and the how you preprocessed it: what is the number of samples, what is the number and type of features (i.d. categorical or numerical) and for supervised learning tasks, what target are your trying to predict: binary, multiclass (1 out of n_classes) or multilabel (k out of n_classes) classification or continuous variable regression.

Bug tracker

If you think you’ve encountered a bug, please report it to the issue tracker:

https://github.com/scikit-learn/scikit-learn/issues

Don’t forget to include:

  • steps (or better script) to reproduce,
  • expected outcome,
  • observed outcome or python (or gdb) tracebacks

To help developers fix your bug faster, please link to a https://gist.github.com holding a standalone minimalistic python script that reproduces your bug and optionally a minimalistic subsample of your dataset (for instance exported as CSV files using numpy.savetxt).

Note: gists are git cloneable repositories and thus you can use git to push datafiles to them.

IRC

Some developers like to hang out on channel #scikit-learn on irc.freenode.net.

If you do not have an IRC client or are behind a firewall this web client works fine: http://webchat.freenode.net
