When I try to get cols and rows from CUDA GpuMat,
pixel_number = gray.cols * gray.rows
it results in error:
AttributeError: 'cv2.cuda.GpuMat' object has no attribute 'cols'
What is interesting is when I run this script using precompiled opencv-python & opencv-contrib-python 4.7.0, it never throws error. Only when I run it with OpenCV I compiled from source. Did I miss some options?
My CMake command:
CUDA_PATH="/usr/local/cuda-11.4" CFLAGS="-I/usr/local/cuda-11.4/include -I/opt/intel/compilers_and_libraries/linux/mkl/include" LDFLAGS="-L/usr/local/cuda-11.4/lib64" \
