NLTK数据安装问题 [英] NLTK Data installation issues

问题描述

我正在尝试在Mac OSX 10.9上安装NLTK数据. NLTK 3.0文档中提到要设置的下载目录是/usr/share/nltk_data，用于集中安装.但是对于这个路径，我得到了错误 OSError:[Errno 13]权限被拒绝:'/usr/share/nltk_data'

I am trying to install NLTK Data on Mac OSX 10.9 . The download directory to be set, as mentioned in NLTK 3.0 documentation, is /usr/share/nltk_data for central installation. But for this path, I get the error OSError: [Errno 13] Permission denied: '/usr/share/nltk_data'

我可以将下载目录设置为/Users/ananya/nltk_data进行集中安装吗?

Can I set the download directory as /Users/ananya/nltk_data for central installation?

我的机器上安装了Python 2.7

I have Python 2.7 installed in my machine

谢谢， 阿南亚

推荐答案

您是否尝试过:

$ sudo python
>>> import nltk
>>> nltk.download()

要检查下载是否正常，请尝试一些已下载的语料库，例如

To check if the downloads work, try a few of the corpora that you have downloaded, e.g.

>>> from nltk.corpus import wordnet
>>> wordnet.synsets('dog')
[Synset('dog.n.01'), Synset('frump.n.01'), Synset('dog.n.03'), Synset('cad.n.01'), Synset('frank.n.02'), Synset('pawl.n.01'), Synset('andiron.n.01'), Synset('chase.v.01')]

如果未正确安装语料库，您将看到以下内容:

If the corpora are not installed properly, you will see something like this:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/nltk/corpus/util.py", line 68, in __getattr__

    except LookupError: raise e
