有没有办法将Gensim LDA输出与pyLDAvis图中的主题相匹配？

Question

我需要处理LDA输出中的主题（lda.show_topics（num_topics = -1，num_words = 100 ...），然后比较我对pyLDAvis图的作用，但主题编号的编号不同。有没有办法我可以匹配吗？

If it's still relevant, have a look at the documentation http://pyldavis.readthedocs.io/en/latest/modules/API.html

You may want to set sort_topics to False . This way the order of topics in gensim and pyLDAvis will be the same.

At the same time, gensim's indexing starts from 0, while pyLDAvis displays topics starting from 1. Not sure if there's a straightforward way to address this.
