[scikit-learn] Help needed

Hi, Li,

to me, it looks like you are importing matplotlib in your code, but matplotlib is not being installed on the CI instances that are running the scikit-learn unit tests. 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.
