import cv2 leads to "segmentation fault"

edit

I had the same issue and solved it as follows:

Check if your linker finds any 3rd party libraries which you have installed on your system (in my case it was "/usr/NX/lib" which came with its own gtk libraries): LD_DEBUG=files python -c "import cv2"

1. If you have installed opencv through a package manager, check your LD_LIBRARY_PATH variable and remove the entries if existent
2. If you have built opencv from source, you have to exclude the folder from the cmake search path (e.g. -D CMAKE_IGNORE_PATH=/usr/NX/lib)

I think you should check if some file like cv.so has been already in your py2's and py3's lib/sitepackages/ (or anywhere in your python's path--

import sys

for i in sys.path:

    print(i)

Only if it's done, the cv2 lib can be found by you python, and then the cv2 can be imported.

Build opencv again and this should be resolved for you: https://github.com/whizzzkid/opencv-c...

Oneline install:

$ curl -fsSL http://bit.ly/OpenCV-Latest | [optirun] bash -s /path/to/download/folder

If it does not work try:

$ gdb python
(gdb) run -c "import cv2"
