In the realm of reinforcement learning, DreamerV3, as described in the paper Mastering Diverse Domains through World Models, has made waves by enhancing performance across various environments, all while utilizing fixed hyperparameters. In this article, we’ll walk you through the steps to install and run DreamerV3 on your machine and troubleshoot any issues you might encounter along the way.

Method 1: Manual Installation

Follow these steps to set up DreamerV3 manually:

• Get Dependencies: Make sure you have Python 3.11 installed. Then, run the following command to install the necessary packages:

pip install -r requirements.txt

• Run Training on DMC Vision: Execute the following command to start the training process:

python3 dreamer.py --configs dmc_vision --task dmc_walker_walk --logdir .logdir

• Monitor Results: Use TensorBoard to visualize your log directories with the command:

tensorboard --logdir .logdir

• Setting Up Atari or Minecraft Environments: For setting up these environments, check the scripts located in envsetup_scripts.

Method 2: Docker Installation

If you prefer using Docker for setting up DreamerV3, you can refer to the instructions included within the provided Dockerfile.

Benchmarks

DreamerV3 has shown exceptional results in several benchmarks:

• DMC Proprio: Low-dimensional inputs with a continuous action space (Budget: 500K). Available on DeepMind Control Suite.
• DMC Vision: High-dimensional images with a continuous action space (Budget: 1M). Check it out at DeepMind Control Suite.
• Atari 100k: Discrete actions across 26 Atari games (Budget: 400K). Learn more at OpenAI Atari.
