I have bulit TorchCraftAI and CherryPi on unbuntu 18.04.

But I got this error when I input this cmd

Sorry Jeremy, I just saw this. The tutorial fell a little out of date. Try adding this line prior to cherrypi::init() in micro_tutorial.cpp: https://github.com/TorchCraft/TorchCraftAI/blob/develop/scripts/botplay/botplay.cpp#L36
