Writer for TrainValidationSplitModel. param: instance TrainValidationSplitModel instance used to construct the writer

TrainValidationSplitModel supports an option "persistSubModels", with possible values "true" or "false". If you set the collectSubModels Param before fitting, then you can set "persistSubModels" to "true" in order to persist the subModels. By default, "persistSubModels" will be "true" when subModels are available and "false" otherwise. If subModels are not available, then setting "persistSubModels" to "true" will cause an exception.
