OCR Detection using Box Co-ordinates

Can you please tellme how to extract text using co-ordinates of the rectangular box?
I tried varying the kernel length for the same.
I run the same code for different pic image but I cannot see any image being created in Cropped folder

ModuleNotFoundError: No module named 'cv2'

May seem obvious for somewhat seasoned developers.
But cv2 isn't installed by default.

A requirements.txt with the dependencies would already help a lot in setting up a virtual environment & getting started quicker.
