Cuda-10.2 + cuDNN 8.0.1.3 ldconfig error

I have installed cuda-10.2 + cuDNN-8.0.1.3 according to the instructions form the official webiste.

After installation. I am able to run samples for both Cuda and cudDNN.

But when I do the sudo ldconfig or ldconfig it always shows the following error.

sbin/ldconfig.real: /usr/local/cuda-10.2/targets/x86_64-linux/lib/libcudnn.so.8 is not a symbolic link

What is the possible reason? How to resolve this issue? This issue also causes a lot of errors during installation of caffe and other projects. Another issue is cudnn version information is moved to cudnn_version.h file, so some other projects MobileNet-Yolov3 and even Caffe installation who are already reading version information from cudnn.h unfortunately they do not get the cudnn information and throw errors. I have spent two days just resolving this issue.

Hi @asadjavedgujar,
Any specific reason you are trying to run ldconfig?

Thanks!

I was following these installation instructions and they said to do so. (https://github.com/yixindu1573/Caffe-Installation-Ubuntu-16.04-cuda-9.0-cudnn-v7)

Hi @asadjavedgujar,
We suggest you to follow the official document.

Thanks!
