mosaicml/streaming

A Data Streaming Library for Efficient Neural Network Training

57
/ 100
Established

Streams training data from cloud storage (S3, GCS, Azure, OCI) using sharded MDS format with automatic caching and decompression, eliminating the need to pre-download full datasets. Implements distributed-training-aware sampling and shuffling via a drop-in PyTorch `IterableDataset` replacement, supporting images, text, video, and multimodal data with optional compression (zstd).
