When does this happen?
IF Training loss diverges when using gradient accumulation with DeepSpeed enabled, compared to without DeepSpeed.
How others solved it
THEN Update transformers to version 4.46.3 which includes a patch fixing a gradient accumulation bug when using DeepSpeed. If upgrading is not possible, apply the fix from pull request #35157 (huggingface/transformers). Ensure that gradient accumulation steps are correctly synchronized across DeepSpeed ZeRO stages.
pip install transformers>=4.46.3
