             Summary: Can't load PipelineModel that was created in Scala with Python due to missing Interaction transformer
                 Key: SPARK-26970
                 URL: https://issues.apache.org/jira/browse/SPARK-26970
             Project: Spark
          Issue Type: Bug
          Components: ML, PySpark
    Affects Versions: 2.4.0
            Reporter: Andrew Crosby


The Interaction transformer ([https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/ml/feature/Interaction.scala)] is missing from the set of pyspark feature transformers ([https://github.com/apache/spark/blob/master/python/pyspark/ml/feature.py)].

 

This means that it is impossible to create a model that includes an Interaction transformer with pyspark. It also means that attempting to load a PipelineModel created in Scala that includes an Interaction transformer with pyspark fails with the following error:
{code:java}
AttributeError: module 'pyspark.ml.feature' has no attribute 'Interaction'
{code}
