python opencv imshow function not working after upgrading to Macos big sur 11.1
I have recently upgraded to Mac big sur 11.1 , after this upgrade python opencv imshow and video functions are not working. It was working before the upgrade. I don't know what is wrong with this now. It is basic imshow function. Please help me to get this issue resolved.
Thanks in advance
