Production Reinforcement Learning with Modern Open-Source Frameworks
Research Disclaimer This tutorial is based on: Stable-Baselines3 v2.2+ (PyTorch-based RL algorithms) Gymnasium v0.29+ (successor to OpenAI Gym) RLlib v2.9+ (Ray distributed RL) Optuna v3.5+ (hyperparameter optimization) Academic RL papers: PPO (Schulman et al., 2017), DQN (Mnih et al., 2015), A2C (Mnih et al., 2016) TensorBoard v2.15+ and Weights & Biases (monitoring) All code examples are production-ready implementations following documented best practices. Examples tested with Python 3.10+ and work on both CPU and GPU. Stable-Baselines3 is the most actively maintained RL library as of 2025. ...
