【问题描述】:
在尝试保存来自具有一个估计器(决策树)的管道的模型管道时,我遇到了这个错误:
Exception in thread "main" java.lang.UnsupportedOperationException: Pipeline write will fail on this Pipeline because it contains a stage which does not implement Writable. Non-Writable stage: dtc_c13531497173 of type class org.apache.spark.ml.classification.DecisionTreeClassificationModel
我在其他估算器上看到过类似的问题,您知道有什么解决方法吗?
谢谢
