   @srowen @luhenry Thanks for pinging me!
   I believe that GMM python test case is quite unstable. I had found that the [way to compute the sum of weights](https://github.com/apache/spark/pull/26735#issuecomment-568451629) can even cause different convergence curves.
   I think this GMM case has wasted too many efforts to verify, and we should apply a more stable case instead.
