When I go to /usr/local/cuda/samples/1_Utilities/deviceQuery
and execute
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

mkdir -p ../../bin/x86_64/linux/release
cp deviceQuery ../../bin/x86_64/linux/release
moose@pc09 /usr/local/cuda/samples/1_Utilities/deviceQuery $ ./deviceQuery
I keep getting
./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
I have no idea how to fix it.

回答1:
Update your NVIDIA driver. At the moment you have the driver which only supports CUDA 6 or lower, and you are trying to use the CUDA 7.0 toolkit with it.
回答2:
I ran into this exact same error message with toolkit 8.0 on ubuntu 1604. I tried reinstalling toolkit, cudnn, etc etc and it didn't help. The solution turned out to be very simple: update to the latest NVIDIA driver. I installed NVIDIA-Linux-x86_64-367.57.run and the error went away.
回答3:
For documentation:
If your nvidia version seems appropriate (see: nvcc -V
), try and simply use the following before getting into anything messy:
sudo ldconfig
回答4:
My cent,
this error may be related to the selected GPU mode (Performance/Power Saving Mode), when you select (with nvidia-settings utiliy) the integrated Intel GPU and you execute the deviceQuery script... you get this error:
-> CUDA driver version is insufficient for CUDA runtime version
But this error is misleading, by selecting back the NVIDIA GPU(Performance mode) with nvidia-settings utility the problem disappears.
It is not a version problem (in my scenario).
