I have already attempted updating numpy. I had to add cv.py to the python2.7 folder in Spyder-Py2 is there something else I need to add?

Answer 1

upgrade numpy to the latest version

pip install numpy --upgrade 

Answer 2

Check the path

import numpy print numpy.__path__ 

For me this was /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy So I moved it to a temporary place

sudo mv /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy \ /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy_old 

and then the next time I imported numpy the path was /Library/Python/2.7/site-packages/numpy/init.pyc and all was well.
