NLTK查找E

Question

在使用NLTK运行Python脚本时，我得到：

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:
**********************************************************************

有人能解释这个问题吗？

Answer 1

使用

>>> nltk.download()

安装缺少的模块（感知器标记器）。

（同时检查Failed loading english.pickle with nltk.data.load的答案）

Answer 2

第一个答案是缺少的模块是“感知器标记器”，实际上它在nltk.download中的名称是“平均感知器标记器”

您可以使用它来修复错误

nltk.download('averaged_perceptron_tagger')

Answer 3

TL；DR

import nltk
nltk.download('averaged_perceptron_tagger')

或下载所有软件包+数据+文档：

import nltk
nltk.download('all')

见How do I download NLTK data?
