I cannot find how to solve the problem like below. The mac is OS 10.10.3 and python is 2.7.6(the original one in mac). All the way to get the scikit-learn is so smooth except testing. I cannot understand the error at all...

failure is listed below:

======================================================================

This is caused by a bug in scipy. Upgrade scipy and it'll go away.
