FAQPage Schema
How do I accelerate reinforcement learning training with vectorized environments?

You can accelerate reinforcement learning training by using a high-performance trainer that runs vectorized environments, allowing rapid rollout collection and logging for your policy network.

Can I use PufferLib for multi-agent distributed training?

Yes, PufferLib supports both single-agent and multi-agent distributed training setups, integrating with Ocean, Gymnasium, and PettingZoo to scale your reinforcement learning workflows.

Does PufferLib work with PyTorch and support torch.compile?

PufferLib requires PyTorch as a dependency and offers optional torch.compile support to optimize and accelerate your reinforcement learning policy network training.

What's the best way to start high-performance PPO training?

The best way to start PPO training is to run the provided training script against your environment, utilizing the built-in PuffeRL trainer with configurable hyperparameters and checkpointing.

Do I need a custom policy network to use PufferLib?

Yes, you need to provide a policy network and environment creation function, after which PufferLib handles rollout collection, logging, and checkpointing for the training loop.
