Error using gym.make

NeurIPS 2020: MineRL Competition
#1

Hi,
I am trying to run the code on Google Colab but getting this error while using gym.make() for minerl environment

BUILD FAILED

Total time: 1 mins 0.464 secs

Minecraft process finished unexpectedly. There was an error with Malmo.

Regards

I am not sure if MineRL runs on Colab, since you need some specific versions of libraries and Java specifically. See docs on installation.

Working Colab example (credit to @tviskaron):

!java -version
!sudo apt-get purge openjdk-*
!java -version
!sudo apt-get install openjdk-8-jdk

!pip3 install --upgrade minerl
!sudo apt-get install xvfb xserver-xephyr vnc4server
!sudo pip install pyvirtualdisplay

from pyvirtualdisplay import Display
display = Display(visible=0, size=(640, 480))
display.start()

import minerl
import gym
env = gym.make(‘MineRLNavigateDense-v0’)

obs = env.reset()
done = False
net_reward = 0

for _ in range(100):
action = env.action_space.noop()

action['camera'] = [0, 0.03*obs["compassAngle"]]
action['back'] = 0
action['forward'] = 1
action['jump'] = 1
action['attack'] = 1

obs, reward, done, info = env.step(
    action)

net_reward += reward
print("Total reward: ", net_reward)

env.close()
