FAQPage Schema
How do I speed up reinforcement learning training for large-scale multi-agent systems?▼

Speed up reinforcement learning training by using high-performance vectorization to optimize parallel environment simulation, achieving 1M-4M steps per second training throughput. This framework is designed specifically for large-scale multi-agent systems and high-throughput tasks.

Does PufferLib work with existing Gymnasium and PettingZoo environments?▼

Yes, PufferLib seamlessly integrates with existing environments from Gymnasium, PettingZoo, and other environment libraries. This allows you to natively set up and train multi-agent systems without rebuilding your simulation environments from scratch.

How do I train a reinforcement learning agent using vectorized environments?▼

Train a reinforcement learning agent by running the quick start script on a standard environment like 'procgen-coinrun'. The framework applies high-performance vectorization to parallelize environment simulation and optimize the overall training pipeline.

What is the best way to run high-throughput parallel training for multi-agent reinforcement learning?▼

The best way to run high-throughput parallel training is using a framework that natively supports multi-agent environment setup and vectorized simulation. This approach optimizes parallel processing to reach millions of steps per second during training.

Do I need PufferLib installed to execute multi-agent training tasks?▼

Yes, you need PufferLib installed to execute these training tasks. It is a required dependency that provides the underlying high-performance vectorization and parallel simulation framework needed to run the reinforcement learning workloads.
