[scikit-learn] Help needed

[Sebastian Raschka]

Honestly not sure what the core dev's preference is, but maybe just submit it as a PR and take the discussion (for a potential removal, inclusion, or move of these features to the documentation) of the additional plotting features from there.

Best,
Sebastian

Or in other words, the Travis instance is trying to execute an "import matplotlib..." and fails because matplotlib is not installed there. Except for the docs, I think matplotlib code is not being tested in scikit-learn's unit tests (and hence, it's not being installed). Does your code/contribution require matplotlib or is it just imported "by accident"? If the latter is true, simply removing matplotlib imports will prob. solve the issue; otherwise, I guess discussing the PR via an issue with the main devs might be the way to go.
