How can I get the stanford NLTK python module?

问题

I have the python (2.7.5) and python-nltk packages installed in Ubuntu 13.10. Running apt-cache policy python-nltk returns:

python-nltk:
  Installed: 2.0~b9-0ubuntu4

And according to the Stanford site, 2.0+ should have the stanford module. Yet when I try to import it, I get an error:

>>> import nltk.tag.stanford
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named stanford

How can I get the stanford module? (Preferably through the usual repositories, since I don't like to install software outside the Ubuntu package manager.)

回答1:

You need to use NLTK downloader:

import nltk
nltk.download()
