After reloading a model the representative docs are not available anymore

[v1alina]

Hey Maarten,

I hope you can help me with an issue I have when reloading my topic model.

I saved my model using Pytorch with both ctf-idf and the embedding model saved as well.
Loading it works just fine but when I run topic_model.get_topic_info() it works fine but the Representative_Docs column only has NaN values. Is that a bug and more importantly is there are way I can get the top three docs for each topic assigned to the column again?

I'm on version 0.16.2

I believe that the representative documents are currently not saved for privacy reasons as they might contain sensitive data. Instead, I would advise saving them separately and then assigning them to topic_model.representative_docs_ when loading the model. Other than that, you can re-calculate the representative documents with _extract_representative_docs but do note that it is a private function which might change in future versions.
