What problem does it solve?
PufferLib removes the friction of building fast, scalable reinforcement learning systems by combining environment design, vectorized simulation, policy architecture, and training into one workflow.
Core Features & Use Cases
- High-throughput training: Run PPO-style experiments with efficient rollout collection, logging, checkpointing, and distributed execution.
- Custom environment development: Use PufferEnv templates to build single-agent or multi-agent environments with clear observation and action space patterns.
- Framework integration: Adapt Gymnasium, PettingZoo, and other external environments into a vectorized RL pipeline.
- Performance tuning: Apply shared-memory vectorization, zero-copy patterns, and optimization guidance to increase steps per second.
- Use case: A research team can prototype a new grid-world task, vectorize it, connect a PyTorch policy, and train it at scale with the provided templates and reference guides.
