ChainerRL Setup

Installing and running ChainerRL

Please refer to ChainerRL's official GitHub for installation instructions and further documentation. Alternatively, you can simply use PyPi to download and install ChainerRL as a package via the following command: pip install chainerrl. Following this, you can simply proceed to testing it out via following the steps laid out in ChainerRL's official getting started guide.

Integration with Marlo

As described previously, ChainerRL interacts with Marlo seamlessly. Let us take the implementation of a PPO agent in Minecraft using ChainerRL and Marlo and break it down into simpler steps.

First it is necessary to start up a Minecraft client on port 10000 such that Marlo can use it. This is very easy to do if you have followed the previous steps and have therefore installed a repacked version of Malmo, since it comes already packed with a Minecraft launcher. Simply navigate to your Malmo folder with your favorite CLI and then:

cd Minecraft
.\launchClient.bat

or

cd Minecraft
.\launchClient.sh

If this is your first time running Malmo, please be patient as building the Gradle client takes a while. Don't worry if the console shows 95% completion as long as the game runs: the server is running and agents will work.

In case you've installed Malmo as a PyPi wheel, you can use the following command:

python3 -c 'import malmo.minecraftbootstrap; malmo.minecraftbootstrap.launch_minecraft()'

You are now ready to start using ChainerRL!
