The Obstacle Tower is an innovative procedurally generated platform that challenges learning agents with a mix of puzzles, planning problems, and escalating difficulty levels. In this guide, we’ll explore how to install and use this captivating environment effectively, alongside troubleshooting tips to enhance your experience.
About the Obstacle Tower
The core objective in the Obstacle Tower is to ascend through multiple floors by reaching the stairs that lead to the next level. Each floor presents unique challenges and procedurally generated elements—much like a video game where the scenery changes each time you play. You must strategize and adapt to move forward successfully.
As you maneuver through different rooms, expect to face diverse challenges that hone your computer vision skills, locomotion abilities, and high-level planning. Success in the Obstacle Tower requires the agent to generalize and adjust to unfamiliar scenarios.
Getting Started
Installation Requirements
- Compatible Operating Systems: Mac OS X, Windows, or Linux
- Python 3.6+
- Unity ML-Agents 1.x
- OpenAI Gym
Step 1: Download the Environment
The binary for the Obstacle Tower will be downloaded automatically upon instantiation. However, you can manually download specific versions if needed:
Step 2: Install the Gym Interface
Run the following commands in your terminal to clone the repository and install the Gym interface:
bash
git clone git@github.com:Unity-Technologies/obstacle-tower-env.git
cd obstacle-tower-env
pip install -e .
Using the Gym Interface
To understand how to interact with the environment, you can refer to the Basic Usage Jupyter Notebook.
Customizing the Environment
Obstacle Tower allows various configurations to tailor its difficulty and content using reset parameters.
Player Control
For a more hands-on approach, you can launch the environment in Player Mode, enabling you to control the agent directly via keyboard:
| Keyboard Key | Action |
|---|---|
| W | Move character forward |
| S | Move character backwards |
| A | Move character left |
| D | Move character right |
| K | Rotate camera left |
| L | Rotate camera right |
| Space | Character jump |
Troubleshooting
While exploring the Obstacle Tower, you may encounter some challenges. Here are some troubleshooting tips:
- If you experience issues with the Unity environment handshake, consider adjusting the
timeout_waitparameter. - For rendering issues or performance slowdowns, make sure to update to the latest version of Unity and ML-Agents.
- If an agent seems to skip levels or encounter freezing, check that the environment is correctly configured and the latest hotfixes are applied.
