yuhao yang commented on SPARK-20768:
------------------------------------
Thanks for the ping. [~mlnick] We should just treat it as an expert param.
Normally in python it should be exposed as a Param in my impression.
> PySpark FPGrowth does not expose numPartitions (expert) param

> Key: SPARK-20768
> URL: https://issues.apache.org/jira/browse/SPARK-20768
> Project: Spark
> Issue Type: Improvement
> Components: ML, PySpark
> Affects Versions: 2.2.0
> Reporter: Nick Pentreath
> Priority: Minor
>
> The PySpark API for {{FPGrowth}} does not expose the {{numPartitions}} param.
> While it is an "expert" param, the general approach elsewhere is to expose
> these on the Python side (e.g. {{aggregationDepth}} and intermediate storage
> params in {{ALS}})
