LeRobot v0.5.0: Scaling Every Dimension

Hugging Face Blog 4 months ago 33

LeRobot released v0.5.0 with support for the Unitree G1 humanoid robot, new vision-language-action policies including Pi0-FAST and Wall-X, and faster dataset processing. The update added over 200 merged pull requests from more than 50 new contributors, expanded robot hardware support to include Earth Rover and OMX Robot, and achieved 10x faster image training and 3x faster video encoding. The modernized codebase now requires Python 3.12 and Transformers v5, enables real-time video encoding during data collection, and allows custom policies to be registered as installable packages.

Ulysses Sequence Parallelism: Training with Million-Token Contexts

Hugging Face Blog 4 months ago 46

Researchers developed Ulysses Sequence Parallelism, a technique that distributes attention computation across multiple GPUs using attention head partitioning to enable training on million-token sequences. The method requires two all-to-all communication operations per attention layer with communication volume of O(n·d/P) per GPU, compared to Ring Attention's O(n·d)—a factor of P times more data. The technique has been integrated into Hugging Face's Accelerate, Transformers Trainer, and TRL's SFTTrainer, allowing standard training workflows to handle sequences of 32,768 tokens or longer without exceeding single-GPU memory limits.
