<p dir="auto">I did not really realize that, but the recent change in multi-output behavior means that there are deprecation warnings for each call to <code class="notranslate">score</code> with multi-output data:</p>
<blockquote>
<p dir="auto">DeprecationWarning: Default 'multioutput' behavior now corresponds to 'variance_weighted' value, it will be changed to 'uniform_average' in 0.18.</p>
</blockquote>
<p dir="auto">Is that desired? Is there a way around it?<br>
And do we want to catch them in the tests?<br>
Currently the test output is HUGE.</p>
<p dir="auto">There are way too many warnings in the test suite, see <a href="https://travis-ci.org/scikit-learn/scikit-learn/jobs/74122431" rel="nofollow">https://travis-ci.org/scikit-learn/scikit-learn/jobs/74122431</a></p>
