------------------------------------
[~yanbo] Current ML models parameters look like must be set as keyword
dictionary type. Specifically, what type of parameters can be set as vector
types?
> PySpark Param of Vector type can be set with Python array or numpy.array

> Project: Spark
> Issue Type: Improvement
> Components: ML, PySpark
> Reporter: Yanbo Liang

> If the type of Param in PySpark ML pipeline is Vector, we can set with Vector
> currently. We also need to support set it with Python array and numpy.array.
> It should be handled in the wrapper (_transfer_params_to_java).
