How can I fix the seeds of the clusters in the normal mixtures clustering method so that it gives a fixed result every time it is run?

Hi there,
I want to use normal mixtures method to cluster my data, but it gives a different result every time it is run. Does anyone know how I can fix the seeds of the clusters?

Usually it is set with Set Random Seed(number) or Random Seed(number) but these do not seem to have effect on normal mixtures platform.
