Description

The documentation of the toArray() method and the values property in pyspark.ml.linalg.DenseVector is confusing.

toArray(): Returns an numpy.ndarray

values: Returns a list of values

However, they are actually aliases and they both return a numpy.ndarray.

FIX: either change the documentation or change  the values property to return a Python list.
