cudaGetDeviceCount returned 30 -> unknown error 错误求助

起因是训练yolov3模型的时候，出现如下错误：
CUDA Error: unknown error
darknet: ./src/cuda.c:36: check_error: Assertion `0' failed.
已放弃 (核心已转储)
然后想测试cuda8.0是否正确运行，就出现了这个错误：
./deviceQuery
./deviceQuery Starting...
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 30
-> unknown error
Result = FAIL
求帮助
