π0.5开源了！！！

Core Viewpoint - The article discusses the release of the π0.5 model, an upgraded version of the π0 model, which enhances open-world generalization capabilities through knowledge insulation [3]. Group 1 - The π0.5 model has been open-sourced and is available on GitHub, providing a base model pre-trained on over 10,000 hours of robotic data [5][4]. - The repository includes practical examples and guidelines for fine-tuning custom datasets, making it accessible for users [5]. - The PyTorch version of both π0 and π0.5 models has been implemented and validated on the LIBERO benchmark, which includes inference and fine-tuning [10]. Group 2 - The π0-FAST model features mixed precision training, fully sharded data parallel (FSDP) training, low-rank adaptation (LoRA) training, and exponential moving average (EMA) weights during training [12].
