Import error (OpenCV) inside OpenVino Environment

[Hartmann__Patrick]

Hello @everyone,

when trying to run an app inside the OpenVino Environment that imports OpenCV I received following Import Error:

Traceback (most recent call last):
  File "app.py", line 2, in <module>
    import cv2
ImportError: dlopen(/opt/intel/openvino_2019.3.376/python/python3/cv2.so, 2): Symbol not found: _PyBytes_AsString
  Referenced from: /opt/intel/openvino_2019.3.376/python/python3/cv2.so
  Expected in: flat namespace
 in /opt/intel/openvino_2019.3.376/python/python3/cv2.so

I ran all verification scripts successfully after installing the toolkit and also was able so far to download pre-trained models from the OpenVino Model Zoo. Does anyone has an idea and or guidance on what I can do about it?

What is your platform and Python version? Add full output of the command:

python3 -c 'import cv2'

Thanks, actually just the change from

python

to

python3

did the trick. Using just "python" refers to an outdated version that comes preinstalled with macOS.
