Pettingzoo

pufferlib is a high-performance reinforcement learning skill for fast parallel simulation, vectorized rollouts, and multi-agent training. Use this pufferlib guide to install, understand pufferlib usage, and adapt RL pipelines with Gymnasium, PettingZoo, Atari, Procgen, or NetHack-style environments. Ideal for code generation focused on throughput and scalable PPO workflows.
