使用 pyLDAvis 将 LDA 主题模型可视化为 AttributeError: 'function' object has no attribute 'num_topics'

我正在尝试使用 pyLDAvis 可视化主题。但是低于错误。请帮助我理解错误并提出纠正方法。

我遇到错误的部分代码

''' pyLDAvis.enable_notebook()

模型 = gensim_lda_model

corpus = [dictionary.doc2bow(doc) for clean_doc_lda 中的 doc]

dictionary = corpora.Dictionary(clean_doc_lda)

vis = pyLDAvis.gensim.prepare(model,corpus,dictionary)

pyLDAvis.display(vis) '''

错误部分如下

''' AttributeError 回溯（最近一次调用最后一次）在

10 字典 = corpora.Dictionary(clean_doc_lda) 11

---> 12 vis = pyLDAvis.gensim.prepare(model,dictionary)

 13 pyLDAvis.display(vis)
