NLTK数据安装问题

Question

我正在尝试在Mac OSX 10.9上安装NLTK数据.如NLTK 3.0文档中所述,要设置的下载目录是/ usr/share/nltk_data,用于集中安装.但是对于这条路径,我得到错误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？

我在我的机器上安装了Python 2.7

谢谢,阿纳尼亚

Answer 1

你有没有尝试过:

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

要检查下载是否有效,请尝试下载一些已下载的语料库,例如

>>> 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')]

如果没有正确安装语料库,您将看到如下内容:

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__
