imitation (HumanCompatibleAI)
Clean implementations of behavioral cloning, DAgger, GAIL, AIRL and more for imitation learning research.
Reliable RL algorithm implementations (PPO, SAC, …) widely used before specialized robot trainers.
Default reliable RL baselines for many robot students
Stable-Baselines3 (SB3) is the default reliable implementation of standard RL algorithms (PPO, SAC, TD3, DQN, …) for many students entering robot learning. It is not robot-specific, but it is the cleanest way to learn on-policy / off-policy loops before specialized stacks like rsl_rl or Isaac Lab trainers.
Pair SB3 with Gymnasium / Gymnasium-Robotics or simple MuJoCo tasks first. Once you need massive parallel locomotion or GPU envs, graduate to robot-native trainers.
On this hub’s Learning Path, SB3 sits in Foundations: get one training curve and one evaluation rollout working before touching VLAs.
