When trying to train the Neutral Network it gives me the exception saying that `openface_server.lua` subprocess has died. One of the suggestions is asking whether the command th is in my PATH. What exactly does that mean, and what should it look like? Thanks!

The reason was because I didn't run the script to download all of the correct models.
