Xusen Yin commented on SPARK-14706: ----------------------------------- Sure. I'll take care of it. There are more issues with CrossValidator, TrainValidationSplit and OneVsRest such as no implementation of _transfer_param_map_from/to_java(), which lead that they cannot be wrapped in another meta-estimator. I'm fixing them together. > Python ML persistence integration test > -------------------------------------- > > Key: SPARK-14706 > URL: https://issues.apache.org/jira/browse/SPARK-14706 > Project: Spark > Issue Type: Test > Components: ML, PySpark > Reporter: Joseph K. Bradley > > Goal: extend integration test in {{ml/tests.py}}. > In the {{PersistenceTest}} suite, there is a method {{_compare_pipelines}}. > This issue includes: > * Extending {{_compare_pipelines}} to handle CrossValidator, > TrainValidationSplit, and OneVsRest > * Adding an integration test in PersistenceTest which includes nested > meta-algorithms. E.g.: {{Pipeline[ CrossValidator[ TrainValidationSplit[ > OneVsRest[ LogisticRegression ] ] ] ]}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
