There are several ways to get in touch with the developers.
Some scikit-learn developers support users on StackOverflow using the [scikit-learn] tag.
For general theoretical or methodological Machine Learning questions stack exchange 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 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
or continuous variable regression.
If you think you’ve encountered a bug, please report it to the issue tracker:
Don’t forget to include:
steps (or better script) to reproduce,
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
Note: Gists are Git cloneable repositories and thus you can use Git to push datafiles to them.
