I have installed OpenCV and when trying to import cv2 in python, I get the following error. The import was working fine until I installed/un-installed and re-installed tensor flow.

OpenCV has been installed in a conda environment using cmake. Any idea how to fix this?

I got around a similar issue by doing:

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libffi.so.7
