Fail to make environment : Minecraft Process finished unexpectedly

NeurIPS 2019 : MineRL Competition
#1

Hello,

When following the Hello World tutorial : http://www.minerl.io/docs/tutorials/first_agent.html

and executing :

env = gym.make('MineRLNavigateDense-v0')

The following error is raised :

/anaconda3/lib/python3.6/site-packages/minerl/env/malmo.py in __init__(self, port, existing)
    258 
    259             # Launch the instance!
--> 260             self.launch(port, existing)
    261 
    262 

~/anaconda3/lib/python3.6/site-packages/minerl/env/malmo.py in launch(self, port, existing)
    286                     logger.debug("\n".join(line.split("\n")[:-1]))
    287                     if not line:
--> 288                         raise EOFError("Minecraft process finished unexpectedly")
    289                     client_ready =  "CLIENT enter state: DORMANT" in line
    290                     server_ready =  "SERVER enter state: DORMANT" in line

EOFError: Minecraft process finished unexpectedly

I work on Ubuntu 18.04 and have installed openjdk-8 as described in the installation tutorial : http://www.minerl.io/docs/tutorials/getting_started.html

Has this happened to anyone ?

Best,

Is that possible to run the environment via 'ssh' with a headless server?
#2

This happened to me when running the package out of a docker container -> forgot that I hard restarted this morning and had to do xhost + to allow external connections to the display

can’t say if the error is due to the same reasons, but it could be the case that your xhost doesn’t allow the connection from the client the Minecraft process is running from

#3

This also happened to me because the process had no write permissions in the python directory. This was solved by installing minerl using “pip install --upgrade --user minerl”

#4

Hi @vihanga, @anyonic_ai,

Thank you both for your answers. I have uninstalled minerl and reinstalled it with --user, I have also done xhost + but it still fails.

I use ssh to work remotely so this might be a factor.

#5

Does your remote machine have a head? If so, are you exporting your display before running? export DISPLAY=:0 will let you run MineRL Env with GPU acceleration by using the remote display

#6

Please add the following to your code.

import logging
logging.basicConfig(level=logging.DEBUG)

That should give us a more detailed error.

Also please upgrade minerl.

Hi @william_guss after adding what you suggested I obtain :

(I have also updated minerl.)

Hi @BrandonHoughton,thank you for your answer, I am not sure what you mean by a head ?

I have tried export DISPLAY=:0 on my remote computer but the same error occurred. I have copied the full error above.

#9

Sorry, to clarify by head I meant a physical display attached to your graphics card.

#10

@william_guss this is a new error to me, you?

#11

This is an issue with Minecraft forge! Good catch. I have implemented some changes that may fix this.
Can you upgrade your minerl package:

pip3 install --upgrade minerl
#12

Hello,

Thank you both for your answers, it all works now ! :slight_smile:

Some more information about the issue :

  • Running env = gym.make("MineRLObtainDiamondDense-v0") on my remote machine via TeamViewer made it work.

  • It did not work when doing it via ssh -X. However upgrading minerl as told by @william_guss solved this issue.

Thanks,
