这段代码中的以下几句是将训练时保存的动态图模型文件导出成推理引擎能够加载的静态图模型文件：

arg_dict = {} if not hasattr(model.export, 'arg_dict') else model.export.arg_dict
args = parse_model_args(arg_dict)
kwargs = {key[2:]: getattr(args, key[2:]) for key in arg_dict}
model.export(args.save_dir, name=args.save_name, **kwargs)

其中 `model.export` 是将动态图模型导出成静态图模型的方法。导出后的模型文件可以被推理引擎加载和使用。
