PPO Agent Playing LunarLander-v2

This is a trained model of a PPO agent playing LunarLander-v2. The agent has been trained with a custom PPO implementation inspired to a tutorial by Costa Huang.

This work is related to Unit 8, part 1 of the Hugging Face Deep RL course. I had to slightly modify some pieces of the provided notebook, because I used gymnasium and not gym. Furthermore, the PPO implementation is available on GitHub, here: https://github.com/micdestefano/micppo.
