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/
Find where the cv2.so is, for example /usr/local/lib/python2.7/dist-packages, then add this into your ~/.bashrc by doing:
sudo gedit ~/.bashrc
and add
export PYTHONPATH=/usr/local/lib/python2.7/dist-packages:$PYTHONPATH
In the last line
And then remember to open another terminal, this can be work, and I have solve my problem. Hope it can help you.
