标签：perl tac ref different python command test opencv bsp
Some day I updated my openCV to the latest version 2.4.13, while recently I found I always get "2.4.8" when I check the version in python2.7. It is wired and anoiying. Also it is normal in C++.
This bug is quite similar with this one: opencv have different version with python module. Luckily the answer works. Also refer to PyImageSearch article - Install OpenCV 3.0 and Python 2.7+ on Ubuntu.
It is related to the symbolically link problem. I was wasting time reinstalling openCV-2.4.13 for several times.
In all, after installing the new version of openCV, one more step is needed. We need to symbolically link our newly created library file -cv2.so- to our python package path.
Let‘s say
/usr/local/lib/python2.7/site-packages/cv2.so: symbolic link to `/usr/lib/python2.7/dist-packages/cv2.so‘
which is usually the case.
We need to remove that symbolic link with ‘rm‘ and create a new one with this command:
ln -s ~path to your new cv2.so file ~/usr/local/lib/python2.7/site-packages/cv2.so
here it shall be
ln -s /usr/local/lib/python2.7/site-packages/cv2.so ~/usr/local/lib/python2.7/site-packages/cv2.so
Make python2.7 use the right version of opencv
