issues with cltorch backend

[quentaluminum]

I have an AMD gpu so cuda is off the table. I have cltorch installed, however when i try to run neural-style.lua in torch I get this error:

Again I can't use cuda or cutorch because i have an amd processor. In the tutorial it says that cltorch is supported, but again it wants to reference files that are impossible for me to install. I've tried installing cuda and cutorch anway, but cutorch immediately recognized my invalid hardware.
I'm new to linux and everything torch, so this is like all a little giberish! thank you for your time.

The lua-based Torch is outdated. It is no longer straightforward to get it to work with newer NVIDIA GPUs either (noticed this when I upgraded from 1080Ti to RTX Titan).

I would recommend you have a look at pytorch and https://github.com/ProGamerGov/neural-style-pt instead.
