Is there any way to extract coherence scores from already saved BERTopic model?

[Jiseong-Michael-Yang]

I want to compare the coherence scores of the models I trained to select an optimal number of topics.

bertopic = BERTopic()
mod = bertopic.load(myModel)

However, mod.__dict__ returns the only the folloiwng information:

Can I get a coherence score from the model?

It is not possible to extract the coherence score from BERTopic as there is no single best way to perform evaluation in topic modeling. Instead, I would advise using OCTIS for evaluating your topic model.
