运行 Gensim LDA 时出现问题

Question

我正在尝试运行此处描述的分布式 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

按照它的建议，通过“将语料库膨胀[ing] 到 1M 个文档，通过反复重复其文档”

我正在使用 python 3.3 和 numpy 1.9.2 我不断收到以下错误：

Exception in thread oneway-call:
Traceback (most recent call last):
  File "/usr/lib64/python3.3/threading.py", line 901, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.3/site-packages/Pyro4/core.py", line 1484, in run
    super(_OnewayCallThread, self).run()
  File "/usr/lib64/python3.3/threading.py", line 858, in run

    self.processjob(job)
  File "/usr/lib64/python3.3/site-packages/gensim/utils.py", line 98, in _synchronizer
    result = func(self, *args, **kwargs)
  File "/usr/lib64/python3.3/site-packages/gensim/models/lda_worker.py", line 80, in processjob
    self.model.do_estep(job)
  File "/usr/lib64/python3.3/site-packages/gensim/models/ldamodel.py", line 480, in do_estep
    gamma, sstats = self.inference(chunk, collect_sstats=True)
  File "/usr/lib64/python3.3/site-packages/gensim/models/ldamodel.py", line 423, in inference
    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，它运行良好，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.

谁能解释我做错了什么？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？

这是 gensim 中的一个错误，由 here 提出。
