cv2.imshow error

[Sumedhsonkamble]

Hand Tracking | OpenCV | python

Facing an error due to this command
cv2.imshow ('Image', img)

cv2.error: OpenCV(4.5.2) C:\Users\runneradmin\AppData\Local\Temp\pip-req-build-k1ohfcms\opencv\modules\highgui\src\window.cpp:404: error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'cv::imshow'

When I comment out the above command, the script is running fine giving all the desired results but without the image.

I checked with the OpenCV versions
Uninstalled opencv from pip and reinstalled using Anaconda but no change.

I studied from the same channel and I have uploaded the handTracking module taught by this teacher, you can copy the code from there, there are few minor changes according to the new versions of media pipe

[Sumpy1]

Mediapipe newer version has an additional argument called model_complexity, if you add that your code should work fine.
You can refer here if you want to see the changes:
