I have an Ubuntu 14.04 system, on which I want to install OpenCV and use it with Python 2.x.
I installed OpenCV using the instructions here: https://help.ubuntu.com/
Create a symbolic link to OpenCV. Eg:
cd ~/.virtualenvs/cv/lib/python2.7/site-packages/ ln -s /usr/local/lib/python2.7/dist-packages/cv2.so cv2.so ln -s /usr/local/lib/python2.7/dist-packages/cv.py cv.py
