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

AI Impact Summary

Hugging Face now hosts Stable-Baselines3 models on the Hub, enabling repositories to store and share SB3 agents and assets. The integration provides load_from_hub and push_to_hub workflows via the huggingface_sb3 and huggingface_hub libraries, with example repos like sb3/demo-hf-CartPole-v1 and ThomasSimonini/demo-hf-CartPole-v1. This accelerates collaboration and reproducibility in RL experiments but increases dependency on Hugging Face Hub availability for model storage and retrieval.
