visualize_topics() 's problem

[zzzxiaoyu]

when i use visualize_topics1 = topic_model.visualize_topics()
it comes to
File "D:\PyChram\BertTopic_Project\Dji\Dji_patent.py", line 52, in
visualize_topics1 = topic_model.visualize_topics()

A small tip, whenever you share an error log, make sure to always your full code and provide enough context. For instance, it's not clear to me which version of BERTopic you are using or if the problem stems from initializing BERTopic for example.

Thus, can you share a bit more information? Also, and this is a bit of a stretch, it might be that you have generated too few topics but I cannot be sure without knowing more about your model.

thanks , I find it was because generated too few topics. I use another data generate 62 topics, it can be visualized.
