person-detector camera error

[kaisark]

I was able to run qlua run.lua --visualize successfully, but the rundemo.lua is failing. Initially, I ran into a deprecated issue and commented out the require 'torchffi' line. I'm not sure if I am running into what might be a camera (Sony Playstation Eye) related issue running the demo (see below).
