I built the master branch on my cluster yesterday and was trying to use the
feature added in this pull request in PySpark. But I got an error message from
the following code. Is there anything else I need to do to use this in PySpark?
Or am I using it in a wrong way?
labelIndexer = StringIndexer(inputCol="labelStr", outputCol="label")
indexer = labelIndexer.fit(df)
indexer.invert(inputCol="prediction", outputCol="predictionStr")
AttributeError: 'StringIndexer' object has no attribute 'invert'
Not sure if this is the best place for the question. Let me know if there
is a best place to ask this.
