ppo-LunarLander-v2

What is ppo-LunarLander-v2 ?

ppo-LunarLander-v2 is an implementation of the Proximal Policy Optimization (PPO) algorithm applied to the Lunar Lander v2 environment, a classic problem in reinforcement learning (RL). The goal is to train an agent to land a lunar module on the moon's surface safely and efficiently. This model is designed to solve the LunaLander-v2 task, which involves navigating a spacecraft to a designated landing area while avoiding obstacles and maintaining controlled descent.

Features

• PPO Algorithm: Utilizes the PPO reinforcement learning algorithm for stable and efficient training.
• Lunar Lander Environment: Optimized for the Lunar Lander v2 environment from the Gym library.
• Continuous Action Space: Supports continuous control actions for precise movement and landing maneuvers.
• Pre-Trained Model: Comes with a pre-trained model for immediate use and evaluation.
• Customizable Policies: Allows for customization of policies and hyperparameters for specific use cases.

How to use ppo-LunarLander-v2 ?

1. Install Required Libraries: Ensure you have the Gym library installed to run the Lunar Lander environment.

   pip install gym
   

2. Import and Initialize: Import the environment and initialize the PPO model.

   import gym
   from ppo_lunarlander_v2 import PPOLunarLander
   env = gym.make('LunarLander-v2')
   model = PPOLunarLander.load('path/to/model')
   

3. Run the Model: Use the model to control the lunar lander and observe the behavior.

   obs = env.reset()
   while True:
       action, _states = model.predict(obs)
       obs, rewards, done, info = env.step(action)
       env.render()
       if done:
           break
   

4. Evaluate Performance: Monitor the agent's performance and adjust policies as needed.
