Implements and optimizes reinforcement learning agents using the Stable Baselines3 library for PyTorch.
This skill provides comprehensive support for reinforcement learning (RL) workflows using the Stable Baselines3 (SB3) library. It guides users through the entire development lifecycle, from designing custom Gymnasium environments and selecting the right algorithms—such as PPO, SAC, or DQN—to implementing advanced training techniques like vectorized environments and custom callbacks. Whether you are building robotics controllers or game-playing agents, this skill provides the patterns and best practices needed for robust model training, evaluation, and performance monitoring within a PyTorch-based ecosystem.
