Problems with model.visualize_topics()

[mediote]

Topic number 0 does not appear when using topic model.visualize_topics(), however in model.get_topic_info(), it appears.
I'm using the latest version of BERTopic.

Thank you for posting this! It seems that I intended to remove outliers in two places, which instead removes the first actual topic. I'll make sure to fix this in the next release!

[MaartenGr]

I just pushed the fix to the master branch, so you can get it already there! The next release might take a while but for now, you can get the most recent version there.

In that case, which will topic number indicate the outlier cluster?

[MaartenGr]

Typically, -1 represents the outlier cluster but the documents contained do not actually represent a topic or cluster. For the sake of simplicity, it was added as a topic but is not something that is easily interpretable. Therefore, it is excluded from the visualizations since it is actually not something that should be compared with the other topics.
