Belief Propagation over Factor Graph and its Factor Nodes from Markov Network

[qillbel]

Subject of the issue

Dear Author(s),
I have 2 questions:

1. I searched in the book, but I failed to find how can I run Belief Propagation over a Factor Graph with pgmpy?
2. When we convert a Markov network into a Factor Graph (FG_Model = MarkovModel.to_factor_graph()), does it also carries the factors in Markov Network into factor nodes, in the Factor Graph?

Thank you very much.
