Enthought Canopy --- error in using sklearn

Question

I just installed Enthought Canopy on an Imac Os 10.6.8. I get an error message (appended below) when I try to test sklearn. The error is ImportError: numpy.core.multiarray failed to import. It looks like the wrong version of numpy is being used. I'm not sure how to fix.

Answer 1

I discovered that I had in my PYTHONPATH (as defined in my .profile) /Library/Python/2.6/site-packages from where the wrong version of numpy was being picked up. Eliminating this corrected the problem.
