Question

我正在尝试使用NLTK进行Python中的NLP学习。

某些名为“panlex_lite”的软件包一直给我错误，所以我尝试使用以下代码：

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

无论如何解决这个问题？我尝试过使用“halt_on_error = False”方法，但它仍然给我错误。

感谢。

在这里＆＃34;脏＆＃34;劈：

$ 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')

另外，请尝试earthy：

pip install earthy

<强> 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.

完全下载panlex_lite：

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

下载非本地托管在nltk_data github上的所有第三方数据集：

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

NLTK panlex_lite给我错误
