cuda - 我能对 'CUDA driver version is insufficient for CUDA runtime version' 做什么？

Question

当我去 /usr/local/cuda/samples/1_Utilities/deviceQuery并执行

moose@pc09 /usr/local/cuda/samples/1_Utilities/deviceQuery $ sudo make clean
rm -f deviceQuery deviceQuery.o
rm -rf ../../bin/x86_64/linux/release/deviceQuery

moose@pc09 /usr/local/cuda/samples/1_Utilities/deviceQuery $ sudo make
"/usr/local/cuda-7.0"/bin/nvcc -ccbin g++ -I../../common/inc  -m64    -gencode arch=compute_20,code=sm_20 -gencode arch=compute_30,code=sm_30 -gencode arch=compute_35,code=sm_35 -gencode arch=compute_37,code=sm_37 -gencode arch=compute_50,code=sm_50 -gencode arch=compute_52,code=sm_52 -gencode arch=compute_52,code=compute_52 -o deviceQuery.o -c deviceQuery.cpp

mkdir -p ../../bin/x86_64/linux/release
cp deviceQuery ../../bin/x86_64/linux/release

moose@pc09 /usr/local/cuda/samples/1_Utilities/deviceQuery $ ./deviceQuery

我不断得到

./deviceQuery Starting...

CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 35 -> CUDA driver version is insufficient for CUDA runtime version Result = FAIL

我不知道如何解决它。

更新您的 NVIDIA 驱动程序。目前，您拥有仅支持 CUDA 6 或更低版本的驱动程序，并且您正在尝试使用 CUDA 7.0 工具包。
