The MineRL environment is obviously very different from the demonstration environment. For example, the humans that provided the demonstrations had a higher-resolution view, had audio input, could see and restore health, could craft ladders and swords, etc. Of course, transfer learning may be valuable despite these differences.
One difference that seems significant and may be worth fixing is that MineRL agents are not able to put torches on walls. It’s funny to see. Do y’all have any plans to fix that bug with
action['place'] = 'torch'?
And, a secondary question: Does
action['nearbySmelt'] = 'coal' actually do anything?
