Insufficient memory

[Dhruv00710]

sir I made OMR program in python version 3.11.4 32 bit version and its get problem about memory. and i am not use python 64 bit version because i also use twain library for scan OMR sheet and twain library is work on 32 bit and in 64 bit python its not show the scanner. so i use 32 bit library.
Error like :
res = cv2.matchTemplate(
^^^^^^^^^^^^^^^^^^
cv2.error: OpenCV(4.8.0) D:\a\opencv-python\opencv-python\opencv\modules\core\src\alloc.cpp:73: error: (-4:Insufficient memory) Failed to allocate 4380856 bytes in function 'cv::OutOfMemoryError'

Oh darling
I am sorry. I'm on linux platform.
If u wanna try other opencv version u would better to build from source.

Finding out the bug took me 1 day and i didn't sleep 20hours.
The problem for me was having 2 opencvs version.
Libopencv-dev and custom installation of opencv 4.8.0.
Choose 1 opencv and stick to it.
