zhengruifeng commented on issue #26882: [SPARK-30247][PySpark] GaussianMixtureModel in py side should expose gaussian URL: https://github.com/apache/spark/pull/26882#issuecomment-566404111 Sorry for the late reply. It seems we need to add a corresponding class `MultivariateGaussian` containing a vector and a matrix in the py side, otherwise the `gaussian` can not be used in the py side. ```python In [8]: model.gaussians Out[8]: [{'__class__': 'org.apache.spark.ml.stat.distribution.MultivariateGaussian'}, {'__class__': 'org.apache.spark.ml.stat.distribution.MultivariateGaussian'}, {'__class__': 'org.apache.spark.ml.stat.distribution.MultivariateGaussian'}] ```
