我正在尝试运行分布式LDA示例,如下所述：

我按照以下教程创建了一组文档：

通过“将文件扩展到1M文件,通过重复其文件”来表示

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:
Traceback (most recent call last):

    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()

我运行分布式lsi示例,它运行正常,但由于某种原因,我似乎无法使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.

有人能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？

解决方法:

这是gensim中的一个bug,它被提升了here.
