<p>There are several ways to get in touch with the developers.</p>
<div class="section" id="mailing-list">
<span id="mailing-lists"></span><h2>Mailing List<a class="headerlink" href="#mailing-list" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>The main mailing list is <a class="reference external" href="https://mail.python.org/mailman/listinfo/scikit-learn">scikit-learn</a>.</li>
<li>There is also a commit list <a class="reference external" href="https://lists.sourceforge.net/lists/listinfo/scikit-learn-commits">scikit-learn-commits</a>,
where updates to the main repository and test failures get notified.</li>
</ul>
</div>
<div class="section" id="user-questions">
<span id="id1"></span><h2>User questions<a class="headerlink" href="#user-questions" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>Some scikit-learn developers support users on StackOverflow using
the <a class="reference external" href="http://stackoverflow.com/questions/tagged/scikit-learn">[scikit-learn]</a>
tag.</li>
<li>For general theoretical or methodological Machine Learning questions
<a class="reference external" href="http://stats.stackexchange.com/">stack exchange</a> is probably a more
suitable venue.</li>
</ul>
<p>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.</p>
<p>Code and data snippets are welcome. Minimalistic (up to ~20 lines long)
reproduction script very helpful.</p>
<p>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
<code class="docutils literal"><span class="pre">n_classes</span></code>) or multilabel (<code class="docutils literal"><span class="pre">k</span></code> out of <code class="docutils literal"><span class="pre">n_classes</span></code>) classification
or continuous variable regression.</p>

<div class="section" id="bug-tracker">
<span id="id3"></span><h2>Bug tracker<a class="headerlink" href="#bug-tracker" title="Permalink to this headline">¶</a></h2>
<p>If you think you’ve encountered a bug, please report it to the issue tracker:</p>
<p><a class="reference external" href="https://github.com/scikit-learn/scikit-learn/issues">https://github.com/scikit-learn/scikit-learn/issues</a></p>
<p>Don’t forget to include:</p>
<blockquote>
<div><ul class="simple">
<li>steps (or better script) to reproduce,</li>
<li>expected outcome,</li>
<li>observed outcome or python (or gdb) tracebacks</li>
</ul>
</div></blockquote>
<p>To help developers fix your bug faster, please link to a <a class="reference external" href="https://gist.github.com">https://gist.github.com</a>
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 <code class="docutils literal"><span class="pre">numpy.savetxt</span></code>).</p>
<p>Note: gists are git cloneable repositories and thus you can use git to
push datafiles to them.</p>
