title: attribute error on numpy import with python 2.7 and wxpython
body: <p>I am struggling to get an ide working for python 2.7 with numpy, scipy, matplotlib and wxpython/PyQt installed. Running the ide spyder throws up the message "module 'object' has no attribute 'core'" for numpy. Same message occurs while "from numpy import *" on IDLE.<br>
  Here is the whole message. Please help. Thanks!
