TypeError: a bytes-like object is required, not 'NoneType'
Hi , I have this issue when running on the docker image built for BASLAT2022. I also checked MineRL Java and JDK versions. running other MineRL environments on this iage like HumanSurvival or MineRLBasaltFindCave does't has this issue.
test.py :
import gym import minerl
env = gym.make("MineRLNavigate-v0") # A MineRLNavigate-v0 env obs = env.reset() print('done reset'+'*'*100) # the reset was never finished
log output :

Hey. Could you paste exactly what command you used to install MineRL, what you run (exactly) and the full output log? We have not shared any prebuilt docker images, only the Dockerfile for building an image, but that has not been updated in a while. You should use the instructions in the README of this repo.
Hi, thanks for replying, I just built another conda environment and the error persists. I ran installation of JDK8 beforehand with :
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jd

Hi, just wondering if there is any available docker image with MineRL installed that we could use.
@CooLeee Sorry for the delay. There is no prebuilt image of MineRL itself from the MineRL team, although someone might somewhere have a prebuilt image for this. Check e.g., MineDojo.
