I have installed NLTK module but when I try to install the data I am getting the error below.

enter image description here

>>>import nltk
>>> nltk.download('punkt')
[nltk_data] Error loading punkt: <urlopen error [Errno 11004]
[nltk_data]     getaddrinfo failed>
False

How should I install the data?

    Just type in `nltk.download()` and then find the package you want. Error message implies to me that the package isn't called `punkt`, which I believe is the case. It's called something else. – Slater Victoroff Aug 08 '17 at 16:47

    A [lot of useful hints](https://stackoverflow.com/questions/30822131/nltk-package-errors-punkt-and-pickle) what might have gone wrong. – sophros Aug 08 '17 at 16:50
  • tried nltk.download() - error 11004 - getaddrinfo failed – shan Aug 08 '17 at 16:53
  • This seems like [DNS issue](https://stackoverflow.com/questions/5022945/urllib2-urlerror-urlopen-error-errno-11004-getaddrinfo-failed). Could you check HTTP proxy existence in your setup or change it temporarily to download the data? – sophros Aug 08 '17 at 17:05

The issue might be of the Proxy that is setup in the system.

instead of:

>>import nltk
>>nltk.download()

use:

>>nltk.set_proxy('SYSTEM PROXY')
>>nltk.download()

This should solve the problem. And to find the proxy of the system: search proxy in start option of windows.

I understand this is a very old question but wanted to share my experience for anyone who may experience this situation in future. What i did was (in windows 10) -

  1. open command prompt.
  2. set proxies using command: 
    set HTTP_PROXY=http://userid:password@proxyurl:port
set HTTPS_PROXY=http://userid:password@proxyurl:port
set FTP_PROXY=http://userid:password@proxyurl:port
  3. run command: 
    python -m nltk.downloader

I have been struggling with the error from past few days. This little code helped me solve error :
