Can't run environment without internet connection!

[chenjunjie1994]

Hi, I fail to create an environment. My code

import matplotlib.pyplot as plt # import matplotlib.image as mpimg # import numpy as np import minerl import gym import logging logging.basicConfig(level=logging.DEBUG)

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

And the following is all I get

INFO:minerl.env.malmo:Starting Minecraft process: ['/root/anaconda3/lib/python3.7/site-packages/minerl/env/Malmo/Minecraft/launchClient.sh', '-port', '9000', '-env'] Traceback (most recent call last): File "test.py", line 11, in env = gym.make('MineRLNavigateDense-v0') File "/root/jjchen/gym-master/gym/envs/registration.py", line 156, in make return registry.make(id, kwargs) File "/root/jjchen/gym-master/gym/envs/registration.py", line 101, in make env = spec.make(kwargs) File "/root/jjchen/gym-master/gym/envs/registration.py", line 73, in make env = cls(**_kwargs) File "/root/anaconda3/lib/python3.7/site-packages/minerl/env/core.py", line 87, in init self.init() File "/root/anaconda3/lib/python3.7/site-packages/minerl/env/core.py", line 105, in init self.instance = InstanceManager.get_instance().enter() File "/root/anaconda3/lib/python3.7/contextlib.py", line 112, in enter return next(self.gen) File "/root/anaconda3/lib/python3.7/site-packages/minerl/env/malmo.py", line 73, in get_instance inst = cls._Instance(cls._get_valid_port()) File "/root/anaconda3/lib/python3.7/site-packages/minerl/env/malmo.py", line 238, in init self.launch(port, existing) File "/root/anaconda3/lib/python3.7/site-packages/minerl/env/malmo.py", line 266, in launch raise EOFError("Minecraft process finished unexpectedly") EOFError: Minecraft process finished unexpectedly

Can somebody help with it? I run it remotely

[GoingMyWay]

If you run it remotely, I think you can use xvfb-run to run it?

@GoingMyWay

I tried. But it gave the same thing... sad

[chenjunjie1994]

If you run it remotely, I think you can use xvfb-run to run it?

@GoingMyWay

I run the shell file as shown '/root/anaconda3/lib/python3.7/site-packages/minerl/env/Malmo/Minecraft/launchClient.sh', '-port', '9000', '-env',

Then it shows that

================== Is it because environment creating process needs to download something ?

If yes, how can I solve it ? Seems the server I use is not allowed to reach Internet...

@chenjunijie1994 Could you start off by updating the environment? We've made error handling more transparent in version 0.1.11:

pip3 install --upgrade minerl

Currently you need an internet connection to get the environment to start. We're working on some fix for this at the moment, but for now it would be great if you could get internet on your cluster environment.

Thanks a lot. I got error like this.

I set a proxy for gradle. It seems work. But when I tried to start xvfb-run python script.py, it shows errors again. Is it because the machine has a GPU ? I do not have any graphics devices. Thanks.

In order to run minerl environments WITHOUT A HEAD use a software renderer such as 'xvfb': xvfb-run python3 ! NOTE: xvfb conflicts with NVIDIA-drivers! ! To run headless MineRL on a system with NVIDIA-drivers, please start a ! vnc server of your choosing and then `export DISPLAY=:<insert ur vnc server #>

If you're receiving this error and there is a monitor attached, make sure your current displayvariable is set correctly: DISPLAY=:0 python3 ! NOTE: For this to work your account must be logged on the physical monitor.

If none of these steps work, please complain in the discord! If all else fails, JUST PUT THIS IN A DOCKER CONTAINER! :)

Hey could you make a separate issue for this? We can try and diagnose there.
