Answer 1

open your python, check the imported version of your numpy.

It is very likely that you have multiple numpy installed and python always grab the old one, just make sure to delete the old one would fix the problem.

>>> import numpy as np
>>> np.__version__
>>> np.__file__
#if numpy version <= 1.7 would have the error
#find the file and delete it from (np.__file__)

then install the latest numpy if you don't have it
