  1. The topic numbers in the graph are not the same as the numbers in the gensim output! is there any way to solve this?

    • Will be same! the model outputs 10 topic and the graph visualizes 10. you can control how many topics the model will generate by passing num_topics= to LDA() when training the model. Yet you can print out less than 10 topics(when training the model, pass num_topics =10), calling the method model.print_topics(num_topics=5, num_words=10), so the model will show you 5 topics rather than 10.
