使用gensim在LDA之后打印主题分布

Question

我制作了一个示例程序，用于在使用 gensim 进行 LDA 后获取每个文档的主题分布

documents = ["Apple is releasing a new product", 
             "Amazon sells many things",
             "Microsoft announces Nokia acquisition"]   

stoplist=["is","are","am","were","a","me","I"]

texts = [[word for word in document.lower().split() if word not in stoplist] for document in documents]
dictionary = gensim.corpora.Dictionary(texts)
corpus = [dictionary.doc2bow(text) for text in texts]

lda = gensim.models.ldamodel.LdaModel(corpus=corpus, id2word=dictionary, num_topics=2, update_every=1, chunksize=10000, passes=1)
lda.print_topics(2)

但是程序没有打印任何东西。需要进行任何更改吗？
