python3 openCV install error: Symbol not found: _clock_gettime

Question

Can anyone help me fixing an error when importing opencv in python3?

when I import cv2 in python3, I get something like

Traceback (most recent call l         


        

Answer 1

clock_gettime() was added in macOS 10.12. It says so in the error message.

From what I understand it may be possible to build against an earlier Xcode SDK, but the easiest is probably to upgrade to Mac's latest OS.

Answer 2

If you don't want to upgrade your OS, you can install an earlier version of opencv:

pip install opencv-python==3.3.0.10
