Run Ray on TPU, Part 2: Ray AI libraries- Google Developers Blog

За 30 секунд

Что произошло

Google released Ray AI libraries optimized for TPU: Ray Serve for multi-host model serving, Ray Data with iter_jax_batches for efficient batching, and JaxTrainer for distributed JAX training.

Почему это важно

Engineers deploying large language models or training jobs on Google Cloud TPUs who want production-grade serving, data pipelines, and training with automatic slice placement handling.

На что обратить внимание

Multi-host models must declare topology field in config; omitting it causes workers to scatter across slices, hanging jobs silently. JAX imports must occur inside worker functions, not at module scope.
