So, are we implementing the same in Python using numpy or using a wrapper to Scala MultivariateGaussian? I have tried using JavaWrapper class in https://github.com/apache/spark/blob/master/python/pyspark/ml/wrapper.py as wrapper solution. But I am getting constructor errors.( need to pass Vector and DenseMatrix to MultivariateGaussian). Are there any other Wrapper API's i am missing? Kindly, help me out. Thanks, Praveen Here is my code, from pyspark.ml.wrapper import JavaWrapper __all__ = ['MultivariateGaussian'] class MultivariateGaussian(JavaWrapper): #@keyword_only def __init__(self, mu,sigma): super(MultivariateGaussian, self).__init__() self._java_obj = self._new_java_obj( "org.apache.spark.ml.stat.distribution.MultivariateGaussian",(mu,sigma) ) self.mu=mu self.sigma=sigma > Add Python ML API for MultivariateGaussian > -- > > Key: SPARK-15194 > URL: https://issues.apache.org/jira/browse/SPARK-15194 > Project: Spark > Issue Type: Improvement > Components: ML, PySpark >Reporter: holdenk >Priority: Minor > > We have a PySpark API for the MLLib version but not the ML version.
