This is caused by a down-age of Github raw file link.

Meanwhile a stop-gap solution would be to manually download the file:

PATH_TO_NLTK_DATA=/home/username/nltk_data/
wget https://github.com/nltk/nltk_data/archive/gh-pages.zip
unzip gh-pages.zip
mv nltk_data-gh-pages/ $PATH_TO_NLTK_DATA

We're working on finding an alternative to the data and model downloading.

Meanwhile, @everyone please help to check that your script(s) and make sure that you're not overloading the data downloads! Thank you in advance!!

For MacOSX - small modification to the above answer:

PATH_TO_NLTK_DATA=~/nltk_data/
wget https://github.com/nltk/nltk_data/archive/gh-pages.zip
unzip gh-pages.zip
mv nltk_data-gh-pages/packages/ $PATH_TO_NLTK_DATA

Note that this is a big download (~700MB).
