NLTK panlex_lite给我错误 [英] NLTK panlex_lite giving me error

问题描述

我正在尝试使用NLTK在Python中进行NLP学习.

I'm trying to use NLTK for my NLP learning in Python.

某些名为"panlex_lite"的程序包不断给我错误，因此我尝试使用以下程序:

Certain package called "panlex_lite" keeps giving me error so I tried using the following:

import nltk
nltk.download('all', halt_on_error = False)

它给了我以下错误:

[nltk_data]    | Downloading package panlex_lite to
[nltk_data]    |     /Users/Harshil/nltk_data...
[nltk_data]    |   Unzipping corpora/panlex_lite.zip.
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
  nltk.download('all', halt_on_error = False)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/nltk/downloader.py", line 664, in download

outfile.write(contents)
OSError: [Errno 22] Invalid argument

是否要解决此问题?我尝试使用"halt_on_error = False"方法，但它仍然给我错误.

Anyway to fix this? I've tried using "halt_on_error = False" method but it still gives me error.

谢谢.

推荐答案

这是一个肮脏"的骇客:

Here's a "dirty" hack:

$ rm /Users/Harshil/nltk_data/corpora/panlex_lite.zip
$ rm -r /Users/Harshil/nltk_data/corpora/panlex_lite
$ python

>>> import nltk
>>> dler = nltk.downloader.Downloader()
>>> dler._update_index()
>>> dler._status_cache['panlex_lite'] = 'installed' # Trick the index to treat panlex_lite as it's already installed.
>>> dler.download('all')

也可以尝试earthy:

pip install earthy

TL; DR :

import earthy
path_to_nltk_data = '/home/yourusername/nltk_data/'
earthy.download('all', path_to_nltk_data) # Excludes the third party (non-NLTK) packages.

要专门下载panlex_lite:

import earthy
earthy.download('panlex_lite', path_to_nltk_data)

要下载不是本地托管在nltk_data github上的所有第三方数据集，请执行以下操作:

To download all third-party datasets not natively hosted on nltk_data github:

import earthy
earthy.download('third_party', path_to_nltk_data')
