Research direction
Start with the reported deepspeed.initialize() call and inspect the gradient state of model_engine.lm_head.weight afterward. Reproduce the issue using the shown parameter output and establish whether the None gradient and empty tensor are expected; done means clarifying or correcting that behavior with a verified result.
