Gpu API call (unknown error) in mallocPitch #23

Closed shamoqianting closed 6 years ago

I encounter the following problem when I try to extract frames and optical flow images. OpenCV Error: Gpu API call (unknown error) in mallocPitch, file /data1/temporal-segment-networks-master/3rd-party/opencv-2.4.13/modules/dynamicuda/include/opencv2/dynamicuda/dynamicuda.hpp, line 1134 terminate called after throwing an instance of 'cv::Exception' what(): /data1/temporal-segment-networks-master/3rd-party/opencv-2.4.13/modules/dynamicuda/include/opencv2/dynamicuda/dynamicuda.hpp:1134: error: (-217) unknown error in function mallocPitch

Though I delete the build folder and add the line set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS} -arch compute_37 -code sm_37) to CMakeList.txt file, and then rebuild dense_flow, the problem is still there.

Does anyone solve this without reinstalling cuda? Could anyone help me with this? Thank you very much.

It turns out that nvcc option should also be added while compiling opencv. Problem fixed.
