How to set deepspeed's zero2 to save checkpoint, how to set ds_config.json to not save the overall parameter weight of the adapter fusion model?
Does the parameter stage3_gather_16bit_weights_on_model_save work for zero2?

Research direction

Start by checking how ds_config.json handles ZeRO-2 checkpoint saving and whether stage3_gather_16bit_weights_on_model_save applies to that stage. Confirm how adapter-fusion checkpoints handle the overall parameter weights; done means documenting the supported configuration or identifying the required change.
