HI, I upload Mat to GpuMat and then change it by CUDA and the I download GpuMat to Mat. I do not have any problem with Mat up to size 1024x1024, but when my Mat is 2048x2048 I get a error after my CUDA code and in download GpuMat to Mat time!


OpenCV(3.4.1) Error: Gpu API call (unspecified launch failure) in cv::cuda::GpuMat::download, file C:/OpenCV 3.4.1/opencv-3.4.1/modules/core/src/cuda/, line 249

how can I solve it ?
