I’m unable to run the mnist samples, after following the CUDA installation instrucions.

shreyas@shreyas-Predator-G3-571  ~/cudnn\_samples\_v7/mnistCUDNN  ./mnistCUDNN  
cudnnGetVersion() : 7102 , CUDNN\_VERSION from cudnn.h : 7102 (7.1.2)  
Cuda failurer version : GCC 5.4.0  
Error: CUDA driver version is insufficient for CUDA runtime version  
error\_util.h:93  
Aborting…

This is the error I get when I attempt to run the Mnist Sample.

The config is as below:

As you can see I have CUDA 9.1 and the CuDNN version is 7.1.2

You have a 384.xx driver installed with CUDA 9.1 that won’t work.

You should install a R390 driver.
