Research direction
Start by running sh train.sh from the linked sabetAI/rage reproduction and confirm the NaN loss under DeepSpeed mixed precision. Trace the training configuration and loss behavior to isolate whether mixed precision causes the failure; done means the cause is identified and a verified fix or precise diagnosis is provided.
