Opencv-Python built for Windows x64 Python 3.7, .pyd file not found, OpenCV modules unavailable
I'm trying to build opencv-python with cuda. Despite following a few guide, i still can't get it.
https://answers.opencv.org/question/2...
https://lightbuzz.com/opencv-cuda/
https://docs.opencv.org/master/d5/de5...
As per berak's suggestion, I still can't seems to get the OpenCV module for python.
I'm configuring it with CMake GUI and OpenCV Modules shows that python3 is unavailable
I have install the required python packages...
>pip list

Can you share your cmake command?
Are you passing
-DBUILD_opencv_python3=ON
and specifying the locations of your python installas detailed in Accelerate OpenCV 4.3.0 – build with CUDA and python bindings
Thank you for your assistant and the write up on your page.
I follow your checklist, but without much success. Python 3 still classified as unavailable in the OpenCV modules. The CMake GUI cache file and CMake Output
...........................
The CMake command which I configure previously with opencv 4.2 here and Image another link to all the python configuration
...........................
What am I missing out here?
Are you configuring through the cmake gui? If so I would suggest passing the arguments through the command line. From your output it looks like the python config is not complete, specifically Libraries is missing. I get the following cmake output when passing the above PYTHON3 switches to cmake
Can also confirm that you are deleting the build directory every time you change the config?
Surprisingly I managed to get the Python 3 output similar to yours. Let me build them and hopefully the will be something.
I looked into all the python 3 cmake parameters. Indeed in the Cmake cache file, the Python 3 Libraries can't be found, despite the paths being provided. I followed here and added all the parameters Image.
Yes finally it's here!. It's found inside my "opencv-4.3.0\build\lib\python3\Release" cv2.cp37-win_amd64.pyd :') Many thanks!
