echo ' Import site; Site.addsitedir ("/usr/local/lib/python2.7/site-packages") ' >>/users/mac/library/python/2.7/lib/python/ Site-packages/homebrew.pth

2. Find the location of the installation OpenCV library file:

/usr/local/cellar/opencv/2.4.13.2/lib/python2.7/site-packages/cv.py

/usr/local/cellar/opencv/2.4.13.2/lib/python2.7/site-packages/cv2.so

3. Add Environment variables:

Export pythonpath=/usr/local/cellar/opencv/2.4.13.2/lib/python2.7/site-packages/: $PYTHONPATH

4. If import Cv2 is present ImportError:numpy.core.multiarray failed to import, update the NumPy library.

sudo pip install numpy--upgrade--ignore-installed
