nltk download url authorization issue

Question

I tried to update my nltk data with nltk.download() but I got HTTP Error 401: Authorization Required.

When I traced the url in question, I found it in downloader.py<

Answer 1

NLTK have moved from their googlecode site.

As noted in this question, nltk's new data server is located at http://nltk.github.com/nltk_data/. Just update the URL to the new location, and it should hopefully work.
