Ubuntu 16.04, CUDA 8 - CUDA driver version is insufficient for CUDA runtime version

问题:

I've installed the latest nvidia drivers (375.26) manually, and installed CUDA using cuda_8.0.44_linux.run (skipping the driver install there, since the bundled drivers are older, 367 I think).

Running the deviceQuery in CUDA samples produces the following error however:

~/cudasamples/NVIDIA_CUDA-8.0_Samples/1_Utilities/deviceQuery$ ./deviceQuery  ./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 

Version info:

$ nvcc --version

The anwer to similar problems has been updating the nvidia display drivers, though in my case this is already done. Does anyone have any ideas? Thanks.

回答1:

Running

sudo apt-get purge nvidia-* 

and reinstalling the drivers using

sudo apt-get install nvidia-375

solved it. Just for the record, the first time I updated the drivers using the GUI (Additional Drivers tab in Software & Updates).

My cent,

the problem may be related to the selected GPU mode (Performance/Power Saving Mode), when you select (with nvidia-settings utility, in the "PRIME Profiles" configurations) 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(Performance mode) with nvidia-settings utility the problem disappears.

This is not a version problem.

Regards

P.s: The selection is available when Prime-related-stuff is installed. Further details: https://askubuntu.com/questions/858030/nvidia-prime-in-nvidia-x-server-settings-in-16-04-1
