(-2:Unspecified error) OPENCV (4.4.0) ERROR

Question

I’m getting an error (shown below) when I run my program. Does anybody know how to solve it?

#Display the resulting frame
cv2.imshow('frame',frame)

if cv2.waitKey(1) & 0xFF == ord('q'):
    break

#When everything done, release the capture
cap.release()
cv2.destroyAllWindows()

Answer 1

Uninstall the others as before:

pip3 uninstall opencv-python
pip3 uninstall opencv-contrib-python
pip3 uninstall opencv-contrib-python-headless

And then only install the first two:

pip3 install opencv-python==4.4.0.46
pip3 install opencv-contrib-python==4.4.0.46

Answer 2

I had the same error. Reinstalling opencv-python doesn’t solve anything.

Found out that two files are missing from the folder:

age_net.caffemodel
gender_net.caffemodel

Adding both files in the project folder solves the issue.
