@rudyMcgee 以文件形式进行存储

谢谢你的回复，我还是想咨询一下

我用spark多个特征处理算子对原始数据进行处理，最后通过决策树训练分类，请问怎么导出最终模型？

环境：scala 2.11.11，spark2.4，pmml

步骤描述：最近看了你们的这个项目，想仿照写一个小的例子，然后我定义了多个object class，每个class完成一种数据处理功能，然后输出一个新的文件提供给下一个class作为输入，从而完成一连串的数据转换及特征提取工作，最后输出文件用于决策树分类训练，从而得到训练模型。

问题：请问我该如何导出最终训练完的模型的pmml文件？如果只在决策树class中导出pmml模型，那么此pmml模型是不是不包含前面的一串数据处理方法？如果我部署此pmml模型，那么调用的时候是不是不能直接传入源数据？

本人机器学习小白，谢谢帮助
