DeepMind Lab is an innovative 3D learning environment designed for challenging navigation and puzzle-solving tasks. It acts as a testing ground for research in artificial intelligence, primarily focusing on deep reinforcement learning. In this blog, we will guide you through the process of getting started with DeepMind Lab on a Linux system, along with troubleshooting tips to ensure a smooth experience.

Understanding DeepMind Lab: An Analogy

Imagine you are a brave explorer in an expansive, uncharted territory (DeepMind Lab) filled with intricate puzzles (tasks) and hidden treasures (rewards). As you navigate through forests (3D environment), you encounter various challenges that test your skills in problem-solving and decision-making. Each time you solve a puzzle or complete a task, you gain experience (reinforcement learning), enabling you to master the art of exploration more effectively. Just as explorers learn from their journey, agents in DeepMind Lab learn from every interaction with the environment, refining their strategies over time.

Getting Started on Linux

Follow these simple steps to set up DeepMind Lab on your Linux machine:

• First, download Bazel from its official site.
• Clone the DeepMind Lab repository by running the following commands in your terminal:

git clone https://github.com/deepmind/lab
cd lab

• To run a live example of a random agent, execute:

bazel run :python_random_agent --define graphics=sdl -- --length=10000 --width=640 --height=480

• To play as a human, start the game using:

bazel run :game -- --level_script=testsempty_room_test --level_setting=logToStdErr=true

Training Your Agent

DeepMind Lab comes with a pre-built random agent. To train your own agent, utilize the example provided in python_random_agent.py:

bazel run :python_random_agent

For agent-environment interactions, you can refer to the dm_env API documentation.

Troubleshooting Common Issues

Getting started can sometimes come with hurdles. Here are some troubleshooting tips:

• If you encounter build errors, ensure that all dependencies are properly installed and try to update your Bazel installation.
• For any compiler-related warnings, review the BUILD rules that may require editing based on your Linux configuration.
• If you experience performance issues, consider adding the --compilation_mode=opt flag to your commands to optimize performance.
