MineRL Versions

MineRL consists of three unique versions, each with a slightly different sets of features. See full comparison here.

• v1.0: [Code][Docs] This version you are looking at. Needed for the OpenAI VPT models and the MineRL BASALT 2022 competition.
• v0.4: [Code][Docs] Version used in the 2021 competitions (Diamond and BASALT). Supports the original MineRL-v0 dataset. Install with pip install minerl==0.4.4
• v0.3: [Code][Docs] Version used prior to 2021, including the first two MineRL competitions (2019 and 2020). Supports the original MineRL-v0 dataset. Install with pip install minerl==0.3.7

Installation

Install requirements (Java JDK 8 is required. Mac may require additional steps) and then install MineRL with

pip install git+https://github.com/minerllabs/minerl

Basic Usage

Can be used much like any Gym environment:

import gym
import minerl

# Uncomment to see more logs of the MineRL launch
# import coloredlogs
# coloredlogs.install(logging.DEBUG)

env = gym.make("MineRLBasaltBuildVillageHouse-v0")
obs = env.reset()

done = False
while not done:
    ac = env.action_space.noop()
    # Spin around to see what is around us
    ac["camera"] = [0, 3]
    obs, reward, done, info = env.step(ac)
    env.render()
env.close()

Check the documentation for further examples and notes.

Major changes in v1.0

• New Minecraft version (11.2 -> 16.5)
• Larger resolution by default (64x64 -> 640x360)
• Near-human action-space: no more craft and smelt actions. Only GUI and mouse control (camera action moves mouse around).
• Observation space is only pixels, no more inventory observation by default.
