Question about IL and minecraft instance in SQIL

[mahenning]

Hello,

I hope I'm in the right place for this question. In the SQIL fork the issues tab was deactivated.
As I understand it, SQIL learns from pure demonstrations, correct? Thus, I have a few questions:

1. Why do I need to initialize the Java-Minecraft simulator? Isn't just the collected demonstration data not enough?
2. I tried to run your code on a headless machine, but it crashes when trying to open an instance of Minecraft. Is there a way to get around this, or is it possible to run your code on a headless machine? (preferably without sudo rights as I would like to run it on a university cluster).
