Visualizing The Data
To help you get familiar with the MineRL dataset,
minerl python package also provides a data trajectory viewer called
minerl.viewer can load BASALT competition data, but is not yet updated to
equip actions yet.
minerl.viewer program lets you step through individual
showing the observation seen by the player, the action
they took (including camera, movement, and any action described by an MineRL
environment’s action space), and the reward they received.
usage: python3 -m minerl.viewer [-h] environment [stream_name] positional arguments: environment The MineRL environment to visualize. e.g. MineRLObtainDiamondDense-v0 stream_name (optional) The name of the trajectory to visualize. e.g. v4_absolute_zucchini_basilisk-13_36805-50154. optional arguments: -h, --help show this help message and exit
Try it out on a random trajectory by running:
# Make sure your MINERL_DATA_ROOT is set! export MINERL_DATA_ROOT='/your/local/path' # Visualizes a random trajectory of MineRLObtainDiamondDense-v0 python3 -m minerl.viewer MineRLObtainDiamondDense-v0
Try it out on a specific trajectory by running:
# Make sure your MINERL_DATA_ROOT is set! export MINERL_DATA_ROOT='/your/local/path' # Visualizes a specific trajectory. v4_absolute_zucch... python3 -m minerl.viewer MineRLTreechop-v0 \ v4_absolute_zucchini_basilisk-13_36805-50154
The interactor does not function in MineRL version v0.4. If you wish to use this utility,
install an older version of MineRL
pip install minerl=0.3.7.
Once you have started training agents, the next step is getting them to interact with human players.
To help achieve this, the
minerl python package provides a interactive Minecraft client called
minerl.interactor allows you to connect a human-controlled Minecraft client
to the Minecraft world that your agent(s) is using and interact with the agent in real time.
For observation-only mode hit the
t key and type
/gamemode sp to enter
spectator mode and become invisible to your agent(s).
Enables human interaction with the environment.
To interact with the environment add make_interactive to your agent’s evaluation code and then run the minerl.interactor.
env = gym.make('MineRL...') # set the environment to allow interactive connections on port 6666 # and slow the tick speed to 6666. env.make_interactive(port=6666, realtime=True) # reset the env env.reset() # interact as normal. ...
Then while the agent is running, you can start the interactor with the following command.
python3 -m minerl.interactor 6666 # replace with the port above.
The interactor will disconnect when the mission resets, but you can connect again with the same command. If an interactor is already started, it won’t need to be relaunched when running the commnad a second time.
