Issues while verifying the cuDNN installation

I’ve just installed CuDNN on my Ubuntu 18.04.3.
A bit earlier I’ve installed successfully CUDA 10.1.

I followed step by step the Installation guide: https://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html.

2.4 Verifying says:
“To verify that cuDNN is installed and is running properly, compile the mnistCUDNN sample located in the /usr/src/cudnn_samples_v7 directory in the debian file.”

Question how can I access that directory “in the debian file”? Which debian file?

Apparently (please update the guide) I had to download also:

  • cuDNN Runtime Library for Ubuntu18.04 (Deb)
  • cuDNN Code Samples and User Guide for Ubuntu18.04 (Deb)

However, now when I try to run:

sudo dpkg -i libcudnn7_7.6.3.30-1+cuda10.1_amd64.deb

I get the following error:

(Reading database ... 240864 files and directories currently installed.)
Preparing to unpack libcudnn7_7.6.3.30-1+cuda10.1_amd64.deb ...
Unpacking libcudnn7 (7.6.3.30-1+cuda10.1) over (7.6.3.30-1+cuda10.1) ...

2 more suggestions:

  1. Make the documentation open source, so that it could be actively and more accurately maintained
  2. Switch to a better forum, this one lacks a lot of features and is very much of an outdated style
