Stable-Baselines3 now integrated with Hugging Face Hub for hosting and loading RL models

AI Impact Summary

Stable-Baselines3 now integrates with the Hugging Face Hub, enabling hosting and loading of RL agents via hub repos. It enables loading a saved model with load_from_hub and pushing models with push_to_hub, illustrated by the CartPole-v1 PPO example. This lowers friction for sharing and reusing models across environments (e.g., Space Invaders, CartPole-v1) and centralizes model governance in the Hub. Teams should plan for authentication when uploading models and ensure version compatibility between Stable-Baselines3, huggingface_sb3, and the hub client to prevent runtime issues.
