• cloned the repo, went okay

• fail: depends on luarocks, resolution=apt-get went okay -- (undocumented requirement)
• fail: luarocks install nn fails with "lnn.c:4:23: fatal error: nanomsg/nn.h: No such file or directory" (undocumented requirement)

  • fail: npm install nanomsg fails with "Error: failed to fetch from registry: nanomsg" (undocumented requirement)
    • nn depends on nanomsg -- brick wall problem

So. Any suggestions for me?

My suggestion for you is that you install this package on a fresh machine and determine what (rest of) the dependencies are, then document the full installation process.

I would recommend at least Ubuntu 14.04. Please follow the instructions on http://torch.ch/docs/getting-started.html for getting torch installed (which should install all the required dependencies). I have simplified the README a bit to point to this resource.

If you have minimum system requirements, you should state them up front. Otherwise, you may be the cause of expending people's time and effort for no worthy result.

I have installed torch.
It is unable to load the t7 file.
I have changed the t7 file to an explicit path, and it continues to fail to load it.
I have 6 gigs of main memory. Most of it is free. Hundreds of gigs of free space on the HD.
I get the following (non-)results:

Either your colornet.t7 is corrupted or you are running out of memory. I quickly benchmarked it on one of our development systems and the peak RAM usage should be around 2 GiB for the demo in the README. Closing this now as the new error is the same as #7 , use that issue if you continue to have problems.
