There is a mismatch between output["topic-word-matrix"] and dataset.get_vocabulary() in terms of words? #86

There is a mismatch between output["topic-word-matrix"] and dataset.get_vocabulary() in terms of words?

I created a Dataframe as follows:

df = pd.DataFrame(data = output["topic-word-matrix"], columns = dataset.get_vocabulary()).T

When I sort the Dataframe by a topic number to get the top words for a topic, why do the results differ from output["topics"][i]?

Thank you!
