OpenCV Error: Gpu API call (no kernel image is available for execution on the device)

Hi, I encountered an error while running your code. The compile was good. The full log is

(py35) ddeng@ddeng-System-Product-Name:/newdisk/OpticalFlow$ ./opencv 
Usage : ./opencv <frame0> <frame1>
OpenCV Error: Gpu API call (no kernel image is available for execution on the device) in call, file /newdisk/opencv-3.1.0/modules/cudev/include/opencv2/cudev/grid/detail/transform.hpp, line 318
terminate called after throwing an instance of 'cv::Exception'
  what():  /newdisk/opencv-3.1.0/modules/cudev/include/opencv2/cudev/grid/detail/transform.hpp:318: error: (-217) no kernel image is available for execution on the device in function call

Aborted (core dumped)

My PC info:
OS: Ubuntu 16.04
GPU: NVIDIA GTX1080TI
CUDA: 10.0
OpenCV: 3.1.0, which is installed in this directory: /newdisk/opencv-3.1.0/

Do you think this problem is caused by the compilation of OpenCV with CUDA? Hope I can get some hints from you.
