Just to throw in my 3 cents here, I have done some work on moving ROCCA
to use the MineRL’s Gym API to access Minecraft, instead of using a
separate Malmo wrapper.
It works in the sense that I can run the example code in that way and it
simplifies the whole design somewhat, as interfacing with Minecraft is
reduced to relying on a familiar structure of a Gym API.
I also have a setup where I can run the whole thing in a Docker
container, so it’s almost reproducible (there is a minor file edit needed).
That's very cool, Adrian. BTW, anything that doesn't break the existing
examples and doesn't fundamentally change the design for the worst, you
should feel free to create a PR for it.
An idea that I wrote about on Discord was to bring in some unsupervised
image segmentator (like MONet), train it on the MineRL dataset (they
have a dataset of Minecraft traces) and then use that to have some
information about visual objects available to the agent. For now I am
stuck a bit though, as sadly the loading code they provided for their
dataset has memory leak issues, so I will have to write my own, it
shouldn’t prove too difficult as
I just need the video frames but I have to get around to implement it yet.

P.S: BTW, I'm on discord now, my id is ngeiswei.
Do you want to have a call (say Friday, as it's ROCCA day for me)? I
could walk you through the code, to help you decide whether you want to
work on it, or else work on Eva.
