I doubt this is a CQ-editor issue.

opencv/opencv-python#884 (comment)

Maybe check the cv2 versions both from CQ-editor's console, and from the terminal to see if there's a mismatch with the version that CQ-editor is picking up.

import cv2
print(cv2.__version__)

Are you using virtual environments? I would retry with a fresh virtual environment.

[WolsYang]

I try run in virtual environment, but also fail.

Interesting things is, if I type import cv2 in CQ-editor first then press Render green arrow, no error come out.

But if I press Render green arrow first, import cv2 in CQ-editor will fail too.

Please ignore this two log<module 'cv2.dnn'> <class 'cv2.dnn.DictValue'>, this is I add in my ~/.local/lib/python3.10/site-packages/cv2/typing/__init__.py L:162 print(cv2.dnn) print(cv2.dnn.DictValue) .

In that case, try toggling this setting related to watching modules. I think you will need to restart after changing it.
