AI BriefingIntegrated Support for DeepSpeed and FairScale
Key point
It explains how to use the ZeRO features of DeepSpeed and FairScale in the Hugging Face Trainer to improve large-scale model training efficiency.
Details
Starting from Hugging Face transformers v4.2.0, the ZeRO(Zero Redundancy Optimizer) features of DeepSpeed and FairScale are experimentally supported. This helps solve GPU memory shortage issues and maximizes training efficiency for large-scale models.
Key Features and Effects:
- DeepSpeed Integration: Supports CPU offloading, enabling training with larger batch sizes beyond GPU memory limits.
- FairScale (sharded_ddp): Optimizes memory usage by sharding model states.
- Improved Training Efficiency: According to
t5-largemodel benchmark results, using DeepSpeed allows the batch size to be scaled up to 50 compared to the existing DDP method, significantly improving training speed.
Users can easily apply these features through the --deepspeed and --sharded_ddp arguments of the Trainer.
