Weichen Xu updated SPARK-33520: ------------------------------- Summary: make CrossValidator/TrainValidateSplit/OneVsRest Reader/Writer support Python backend estimator/model (was: make CrossValidator/TrainValidateSplit/OneVsRest support Python backend estimator/model) > make CrossValidator/TrainValidateSplit/OneVsRest Reader/Writer support Python > backend estimator/model > ----------------------------------------------------------------------------------------------------- > > Key: SPARK-33520 > URL: https://issues.apache.org/jira/browse/SPARK-33520 > Project: Spark > Issue Type: New Feature > Components: ML, PySpark > Affects Versions: 3.1.0 > Reporter: Weichen Xu > Priority: Major > > Currently, pyspark support third-party library to define python backend > estimator, i.e., estimator that inherit `Estimator` instead of > `JavaEstimator`, and only can be used in pyspark. > CrossValidator and TrainValidateSplit support tuning these python backend > estimator, > but cannot support saving/load, becase CrossValidator and TrainValidateSplit > writer implementation is use JavaMLWriter, which require to convert nested > estimator into java estimator. > OneVsRest saving/load now only support java backend classifier due to similar > issue. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
