 - 🔥deepspeed: 默认为None。可以设置为'zero0', 'zero1', 'zero2', 'zero3', 'zero2_offload', 'zero3_offload'来使用ms-swift内置的deepspeed配置文件
+- zero_hpz_partition_size: 默认为None，这个参数是ZeRO++的特性，即node内模型分片，node间数据分片，如果遇到grad_norm NaN，请尝试使用`--torch_dtype float16`

 - 🔥output_dir: Defaults to None, set as `output/<model_name>`.
 - 🔥gradient_checkpointing: Whether to use gradient checkpointing, default is True.
 - 🔥deepspeed: Defaults to None. It can be set to 'zero0', 'zero1', 'zero2', 'zero3', 'zero2_offload', 'zero3_offload' to use the built-in deepspeed configuration file of ms-swift.
+- zero_hpz_partition_size: Default is `None`. This parameter is a feature of `ZeRO++`, which implements model sharding within nodes and data sharding between nodes. If you encounter grad_norm `NaN` issues, please try using `--torch_dtype float16`

 - 🔥per_device_eval_batch_size: Default is 1.
 - weight_decay: Weight decay coefficient, default value is 0.1.
