Joseph K. Bradley updated SPARK-21221: -------------------------------------- Affects Version/s: (was: 2.1.1) 2.2.0 > CrossValidator and TrainValidationSplit Persist Nested Estimators > ----------------------------------------------------------------- > > Key: SPARK-21221 > URL: https://issues.apache.org/jira/browse/SPARK-21221 > Project: Spark > Issue Type: New Feature > Components: ML > Affects Versions: 2.2.0 > Reporter: Ajay Saini > > Currently, the saving of parameters done in ValidatorParams.scala assumes > that all parameters in EstimatorParameterMaps are JSON serializable. Such an > assumption causes CrossValidator and TrainValidationSplit persistence to fail > when the internal estimator to these meta-algorithms is not JSON > serializable. One example is OneVsRest which has a classifier (estimator) as > a parameter. > The changes would involve removing the assumption in validator params that > all the estimator params are JSON serializable. This could mean saving > parameters that are not JSON serializable separately at a specified path. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
