The error occurred when I tried to fine-tune in single_modality

Research direction
Start with single_modality/engines/engine_for_finetuning.py, especially get_loss_scale_for_deepspeed and its call from train_one_epoch. Reproduce the single-modality fine-tuning path through run_finetuning.py and verify that loss-scale retrieval no longer raises the reported BF16_Optimizer AttributeError.
