    [ https://issues.apache.org/jira/browse/SPARK-10009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14698515#comment-14698515 ] 

Kai Sasaki commented on SPARK-10009:
------------------------------------

[~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?

> 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).
