I found this SO link which might be useful. Maybe try reinstalling scikit-learn after making sure that all dependencies are installed.

This is because you're compiling in a directory that had a previous version, which has left a module lying around. If you use make to do so, it'll be fixed automatically, assuming you're using a reasonably recent version.
