Issue Running MineRL on WSL2 : Minecraft Window Not Showing Up
coolee218 opened this issue · 4 comments
I am attempting to run the code below on WSL2, Python 3.9, MineRL 1.0.0, with both xvfb and VcXsrv installed. However, the expected window of agent playing MC never shows up, and the process continues indefinitely until I interrupt it with keyboard.
test.py
import gym
import minerl
import logging
logging.basicConfig(level=logging.DEBUG)
env = gym.make('MineRLBasaltFindCave-v0')
obs = env.reset()
print('done reset'+'*'*100)
done = False
while not done:
# Take a random action
action = env.action_space.sample()
# In BASALT environments, sending ESC action will end the episode
# Lets not do that
action["ESC"] = 0
obs, reward, done, _ = env.step(action)
env.render()

Hey, sorry for the delay on answer, I have been off the grid.
This is expected; there is no visible window from Minecraft, and you are running an infinite loop of things, so this is expected that you see nothing. You would need to render the image from the observation manually or print some other information to see what is happening.
Hey.
@Miffyli I don't think it's expected because the reset call never successfully finished, it's not the loop.
@coolee218 I had exactly the same issue. You have error: failed to load driver: swrast in the output. For me that was the issue and running
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
fixed it.
I guess malmo or minerl depends on LWJGL which depends on that driver and is, for some reason, unable to load it, so preloading it fixes the issue.
