> --------------------------------------------------------------
>
> Key: SPARK-23828
> URL: https://issues.apache.org/jira/browse/SPARK-23828
> Project: Spark
> Issue Type: Improvement
> Components: ML, PySpark
> Affects Versions: 2.3.0
> Reporter: Bryan Cutler
> Assignee: Huaxin Gao
> Priority: Minor
> Fix For: 2.4.0
>
>
> The Scala StringIndexerModel has an alternate constructor that will create
> the model from an array of label strings. This should be in the Python API
> also, maybe as a classmethod
> {code:java}
> model = StringIndexerModel.from_labels(['a', 'b']){code}
> See SPARK-15009 which added a similar constructor to CountVectorizerModel
