FAQPage Schema
How do I set up high-throughput PPO training with vectorized environments?

PufferLib enables high-throughput PPO+LSTM training by vectorizing environment execution across parallel workers with shared-memory zero-copy data paths. Install via pip, define your environment using PufferEnv or integrate Gymnasium/PettingZoo, then use PuffeRL to run distributed training with built-in logging and checkpointing.

Can I use PufferLib for multi-agent reinforcement learning?

Yes, PufferLib supports multi-agent RL training through vectorized environments and multi-agent support. You can deploy multiple agents per worker, leverage custom PufferEnv environments, and scale across distributed systems while maintaining high throughput.

Does PufferLib work with Gymnasium and PettingZoo environments?

PufferLib integrates directly with Gymnasium, PettingZoo, Atari, and Procgen ecosystems. You can wrap existing environments or build custom ones via PufferEnv, then train PPO+LSTM policies with vectorized parallel simulation across multiple environments per worker.

What's the best way to optimize reinforcement learning for large-scale training?

PufferLib optimizes RL throughput through vectorization, multiple environments per worker, CNN/LSTM policy architectures, and distributed training support. It eliminates bottlenecks via shared-memory zero-copy data paths and provides tooling for training loops, performance tuning, and checkpointing.

How do I integrate custom environments with PufferLib?

Define custom environments using the PufferEnv interface, which supports vectorization and multi-agent scenarios. PufferLib handles environment batching, synchronization, and data management, enabling seamless integration into PPO training pipelines with Gymnasium/PettingZoo compatibility.
