Runtimeerror: module compiled against api version 0xb but this version of numpy is 0xa

Question

Problem :

I am trying to execute below commands.

import numpy as np

import cv

But I am getting following error on my console:

>>> runfile('/Users/isaiahnields/.spyder2/temp.py', wdir='/Users/isaiahnields/.spyder2')

RuntimeError: module compiled against API version a but this version of numpy is 19

Traceback (most recent call last):

ImportError: numpy.core.multiarray failed to import

I have already attempted updating numpy but it is not working. I had added cv.py to the python2.7 folder in Spyder-Py2 is there anything else I need to add?

Pleaase check your path

import numpy

print numpy.__path__

I had also faced the issue in the past. I did research and found solution on it

For me this was as following

/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy

So I just moved it to the temporary place as below:

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 after that the next time I imported numpy the path was as below:

/Library/Python/2.7/site-packages/numpy/init.pyc

and everything started working for me.
