Failed mnistCUDNN test

After installation of cudnn I ran this mnistCUDNN test. And I got the following error:

cudnnGetVersion() : 7605 , CUDNN_VERSION from cudnn.h : 7605 (7.6.5)
Host compiler version : GCC 5.4.0
There are 1 CUDA capable devices on your machine :
device 0 : sms 36 Capabilities 7.5, SmClock 1185.0 Mhz, MemSize (Mb) 7952, MemClock 6001.0 Mhz, Ecc=0, boardGroupID=0
Using device 0

Testing single precision
Cublas failure
Error code 1

I’m working on the Ubuntu 16.04 with cuda 10.1. The driver version for my RTX2070 maxq is 418.56. The cudnn version as you can see from the output is 7.6.5.

And I checked this mnistCUDNN.cpp file. The code in the line 404 is:
checkCublasErrors( cublasCreate(&cublasHandle) );
which indicates that I got the error during creating the cublas handle.

Does any of you guys have similar problems? Please someone help me out! Thanks!

solved with symlink:
$sudo ln -s /usr/lib/x86_64-linux-gnu/ /usr/local/cuda/lib64/
$sudo ln -s /usr/lib/x86_64-linux-gnu/ /usr/local/cuda/lib64/
