Module 'cudnn' not found:No LuaRocks module found for cudnn

Installed Lua and other dependencies following the standard command on Ubuntu 16.04:

conda install lua=5.2 lua-science -c alexbw

I am getting error in the line:

require 'cudnn'

The error is: `

Tried installing cudnn using the command luarocks install cudnn, which gave the output:

Error: No results matching query were found.

How to fix this dependency issue.

It's also available from the alexbw channel, so if you already installed lua-science, just

conda install -c alexbw lua-cudnn

If you're installing from scratch, this seems like a really specialized install, so my recommendation is

conda create -n lua-sci -c alexbw lua=5.2 lua-science lua-cudnn

that is, create a new environment for it.
