Because I am using a lot of stuff based on opencv 2 (ex. ROS and Gazebo) and installing opencv 3 will simply destroy everything, I downloaded the source code of opencv 3 , compiled it and installed it to a local folder in my home directory. Now I want to use that version when running python scripts. What do I need to change? And isn't there any option to make an alternative name spacing on opencv3 ? like for example doing "import cv2_3" in Python?
