我正在尝试运行分布式LDA示例，如下所述：
https://radimrehurek.com/gensim/dist_lda.html
我按照以下教程创建了一组文档：
https://radimrehurek.com/gensim/dist_lsi.html
通过“将文件扩展到1M文档，通过重复其文档”并建议
我正在使用python 3.3和numpy 1.9.2 我一直收到以下错误：
Exception in thread oneway-call:

if doc and not isinstance(doc[0][0], six.integer_types):
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
我运行了分布式lsi示例并且运行正常，但由于某种原因我似乎无法让lda工作。
我尝试将/usr/lib64/python3.3/site-packages/gensim/models/ldamodel.py中的第423行更改为：
if doc is not None and not isinstance(doc[0][0], six.integer_types):
错误消失了，但我收到了警告
FutureWarning: comparison to `None` will result in an elementwise object comparison in the future.
有人可以解释我做错了什么吗？我对此文件的更改是否正确？或者我应该以不同的方式运行LDA？
