Accelerators are getting faster, but is your data loading keeping up? In this video, we explore the Grain Dataset API, a powerful Python library designed to optimize data processing for machine learning. Learn how to build efficient, deterministic data pipelines that ensure your accelerators aren’t left waiting.
Dive into the chaining syntax for transformations—including mapping, shuffling, filtering, and batching. You’ll also discover how to preserve random access for easy debugging and how to implement robust, asynchronous checkpointing with Orbax to save your data loading state alongside your model.
