Cannot find module cv2 when using OpenCV

Question

I am using  Occidentalis OS and have installed OpenCV in it. I get the following message while importing cv2 in a Python program.

pi@raspberrypi~$ python cam.py
Traceback (most recent call last)
File "cam.py", line 1, in <module>
    import cv2
ImportError: No module named cv2

The  cv2.so file is stored in -  /usr/local/lib/python2.7/site-packages/.
Can someone please tell me why this message is popping up and how to solve this?

Answer 1

This is because python is not able to refer to your default site packages folder.

Add these lines in the code:

import sys

sys.path.append('/usr/local/lib/python2.7/site-packages')

Or you can move to /usr/local/lib/python2.7/site-packages directory before running the python command in bash.

I hope this helps.
