luarocks install not working

[angelleng]

Hi there, I installed lua and luarocks as shown and I am not able to install packages using luarocks.

For example when I type luarocks install nngraph it returns

Error: No results matching query were found.

I am able to run the notebooks though.

This is an unfortunate gotcha of a) the luarocks version I'm using and b) luarocks in general. The luarocks that comes with torch adds special packages, like the one you're trying to install. I include the "vanilla" luarocks with my lua distribution. So, if you want to install Torch packages

• Clone the github repo
• cd into it
• luarocks install {path_to_the_rockspec}
