| PyTorch       | PaddlePaddle | 备注                                                   |
| ------------- | ------------ | ------------------------------------------------------ |
| module           | layer      | 需要转换的模型层， 仅参数名不一致。                                    |
| process_group | -            | 统计信息的同步分别在每个进程组内发生， Paddle 无此参数，暂无转写方式。         |
