我正在尝试按此处所述运行分布式LDA示例：https://radimrehurek.com/gensim/dist_lda.html。我按照这里的教程创建了一组文档：https://radimrehurek.com/gensim/dist_lsi.html，通过如其建议的“将语料库重复多次，使其扩展到100万个文档”。我正在使用Python 3.3和numpy 1.9.2，但我一直收到以下错误提示：
错误已经消失了，但是我收到了一个警告信息：

我运行了分布式LSI的实例，它正常运行，但由于某种原因，我似乎无法让LDA工作。
我尝试更改“/usr/lib64/python3.3/site-packages/gensim/models/ldamodel.py”中的第423行：
if doc is not None and not isinstance(doc[0][0], six.integer_types):
错误已经消失了，但是我收到了一个警告信息：
FutureWarning: comparison to `None` will result in an elementwise object comparison in the future.
有人能解释一下我做错了什么吗？我的对这个文件的修改是正确的吗？还是我应该以不同的方式运行LDA？
