Insufficient memory #957

Open Dhruv00710 opened 6 months ago

Dhruv00710 commented 6 months ago

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' and sir please replay me.

Well Iam trying to test opencv 4.5.4 or 4.2.0 they should work. I'll keep u in touch, but it may take a day to reach u. I suggest u to test 4.5.4.

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

Sadegh-Kalami commented 6 months ago

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. GL

nanbwrn commented 3 weeks ago

hi, @Sadegh-Kalami If there are multiple versions of OpenCV installed on the system, how do you ensure that the version being used is the custom 4.8.0 version you installed? I would be extremely grateful, as I've tried many methods without success.

Sadegh-Kalami commented 3 weeks ago

hi, @nanbwrn You can use the command dpkg -l | grep libopencv to list all installed OpenCV packages and their versions. If your output looks like mine, where all packages are version 4.2, you're all set:

If you want to check the specific OpenCV version your project is using, you can add the following lines to your CMakeLists.txt:

find_package(OpenCV REQUIRED)

message(STATUS "Found OpenCV version: ${OpenCV_VERSION}")

When you run CMake, it will output the OpenCV version found, like this:

-- Found OpenCV version: 4.2.0
