Duration Distribution Parameter Update

[TamimAhmEd177]

I am trying to use your library for a segmentation problem. The duration distribution parameters need to be updated per data. I have been trying to update them manually after the resampling. But for some reason throughout the training, the values of the distribution parameters remain the same. I can tell the model is learning from the transition matrix and the observation distribution parameters getting updated per iteration/data. What could be the reason for the duration distribution parameters not getting updated? Or how do you get the updated parameters?
