NLTK查找错误 [英] NLTK Lookup Error

问题描述

在使用NLTK运行Python脚本时，我得到了:

While running a Python script using NLTK I got this:

Traceback (most recent call last):
  File "cpicklesave.py", line 56, in <module>
    pos = nltk.pos_tag(words)
  File "/usr/lib/python2.7/site-packages/nltk/tag/__init__.py", line 110, in pos_tag
    tagger = PerceptronTagger()
  File "/usr/lib/python2.7/site-packages/nltk/tag/perceptron.py", line 140, in __init__
    AP_MODEL_LOC = str(find('taggers/averaged_perceptron_tagger/'+PICKLE))
  File "/usr/lib/python2.7/site-packages/nltk/data.py", line 641, in find
    raise LookupError(resource_not_found)
LookupError:

有人可以解释这个问题吗?

Can anyone explain the problem?

推荐答案

使用

>>> nltk.download()

以安装缺少的模块( Perceptron Tagger ).

to install the missing module (the Perceptron Tagger).

(也请检查没有用nltk加载english.pickle的答案.data.load )
