About

This package allows to run the Minecraft Malmo instance for the minerl contest on any host and allows to access it from another host. The Minecraft instance on the selected host system is not closed to ensure the fastest possible availability. This allows to test the agent code much faster and in case of an error in the agent code you don't have to restart the Minecraft instance again. The host on which the Minecraft instance runs can also be identical to that of the agent.

In addition, the host on which the Malmo instance is running can be on a completely different network and can be accessed without port forwarding. For this purpose a reverse proxy is used, which forwards the requests to this host via an external and publicly accessible server.

Installation

remote-minerl-env requires Python 3.6+ to be installed.

With pip (recommend)

Use the following command to install remote-minerl-env with pip:

pip install remote-minerl-env

You can also very easily update to a newer version:

pip install remote-minerl-env -U

From source

git clone https://github.com/infinityofspace/remote_minerl_env.git
cd remote_minerl_env
pip install .

Usage

After the installation, you can start the remote environment with the following command on the desired host on which you want to run the Minecraft Malmo instance.

remote-minerl-env

All available arguments:

usage: remote-minerl-env [-e ENV_NAME] [-h HOST] [-p PORT] [--help]

optional arguments:
  -e ENV_NAME, --env-name ENV_NAME
                        ID of the minerl environment.
  -h HOST, --host HOST  Host address to bind to.
  -p PORT, --port PORT  Port to bind to.
  --ngrok NGROK_CONFIG_PATH TUNNEL_NAME
                        Use ngrok reverse proxy to expose the environment publicly
  --help                Show the help of the program.

After you have started the remote instance you only need to make minimal adjustments to your existing agent code and then you are done.

You have to use

from remote_minerl_env.environments.client import RemoteClientEnv

env = RemoteClientEnv("<name of the env>")

instead of

env = gym.make("<name of the env>")

That was all. The RemoteEnv also supports the functions step, reset and provides access to the attribute action_space of the original gym environment as class attribute.

Without any additional arguments the instance is only accessible from localhost on port 42424 To expose the Minecraft instance publicly you can use the --ngrok parameter. This uses ngrok to make your local instance accessible from outside your local network:

remote-minerl-env --ngrok /path/to/your/ngrok/config.yml <name-of-the-tunnel-to-use>

The tunnel must be a tcp tunnel and the local mapped port should match the port from the instance, which can be customized with the --port parameter (default port is 42424).
