OpenCV w/CUDA build seems successful, but "import cv2" fails

Now the module is loaded you need to add the below when you are in the python interpreter.

@performlab_rit

os.add_dll_directory(“D://opencv-gpu//opencv_build//bin”)
os.add_dll_directory(“C://Program Files//NVIDIA GPU Computing Toolkit//CUDA//v11.8//bin”)

If that doesn’t work you can use process monitor to track down the missing dll see

Import not possible after build OpenCV with CUDA in Windows 10 (Python3.9)

Did you modify the code from @laurent.berger to point to your Nvidia SDK installation and your intsall location. e.g. for me the below works os.add_dll_directory(‘D:/build/opencv/cuda_build/bin’) os.add_dll_directory(‘C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.7/bin’) If that doesn’t work then you can track down the dll using process monitor by filtering for Process Name = python.exe Operation = Create File and looking for the dll which eventually fails. But if you are no…
