我总共有 54892 个文档，其中包含 360331 个唯一标记。字典长度为 88。
mm = corpora.MmCorpus('PRC.mm')
dictionary = corpora.Dictionary('PRC.dict')
lda = gensim.models.ldamodel.LdaModel(corpus=mm, id2word=dictionary, num_topics=50, update_every=0, chunksize=19188, passes=650)
每当我运行此脚本时，我都会收到此错误：
Traceback (most recent call last):

我在网上查了一下，有人提到我可能与计算机的 RAM 有关。我正在使用具有 4 GB RAM 的 Windows 7 32 位。我应该在脚本中进行哪些更改？
请帮忙！
