2018-12-12 04:52:02 -0500 commented question Where can I find opencv_cudaimgproc320.dll?

opencv tries to cache compiled opencl kernels there. do you (your program) have write access to it ?

2018-12-12 00:17:58 -0500 commented question Transfer data from c++ vector to Mat and displaying it in OpenCV

like mentioned above, you got width and height wrong, and the address of a vector is NOT the address of the 1st element.
