MalmoEnv basic tutorial crash

[trigaten]

I am attempting to use MalmoEnv on Mac
I ran ./launchClient.sh -port 9000 -env which works and launches the client.
Then I ran python3 run.py --mission missions/mobchase_single_agent.xml --port 9000 --episodes 10 in the appropriate directory. This crashed the client with this error:

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':runClient'.
Process 'command '/Library/Java/JavaVirtualMachines/temurin-8.jdk/Contents/Home/bin/java'' finished with non-zero exit value 134

The terminal in which I ran the mission comment showed:

reset 0
Pause before retry on a bytes-like object is required, not 'NoneType'

Any ideas?

I also got this error on Mac. May I ask if you solved the problem after that?

I cant remember if I eventually fixed this. However, Malmo is no longer supported. Use https://minerl.readthedocs.io/en/latest/

Thanks for your reply. I went through the Github of minerl. But I need to use several environments provided in Malmo, which seem not to be provided in minerl. Do you know any documents of building custom environments with minerl?

[trigaten]

Yep, I wrote them! See here: https://minerl.readthedocs.io/en/v0.4.4/tutorials/custom_environments.html

Note that this is not for the most up to date version of the codebase. However, most of the code should work if you choose to use version 1.0.0

Seems interesting, thanks so much.

By the way, can minerl load .xml or other formats file like Malmo?

[trigaten]

I believe so, but you may have to modify the source a bit to do that.
