zero323 commented on issue #27181: [SPARK-30493][PYTHON][ML] Remove OneVsRestModel setClassifier, setLabelCol and setWeightCol methods URL: https://github.com/apache/spark/pull/27181#issuecomment-573479873 > `setLabelCol` is still required. Is it really? [Doesn't seem](https://spark.apache.org/docs/3.0.0-preview2/api/scala/org/apache/spark/ml/classification/OneVsRestModel.html) like Scala counterpart doesn't has one. And ignoring that ‒ when would a `Model` use it?
