I notice the Dockerfile pulls from nvidia/cuda which tells me it could be a cuda based application. Railway doesn't have GPUs so if this is a cuda based application then it might not run on Railway. Although it's possible it isn't cuda based and does support CPU, in which case you could give it a try. Luckily it has a Dockerfile so deployment should be relatively simple.

I skimmed through the docs, I get the feeling it supports CPU, so it could work - only one way to find out though, deploy it and see what happens
