How to use pydlm trained model from a dataset on a new test dataset

[XinLi1202]

I generated a dlm model using pydlm method. How can I apply this model to do the prediction of a new dataset?

from pydlm import dlm, trend, seasonality, dynamic, autoReg, longSeason
myDLM = dlm(dataset1)
myDLM.add(trend(degree=0, discount=0.99, name='trend2'))
filter = myDLM.predict (new dataset) ??

Thank you!
