problem with "from nltk.book import *"

[Katya]

Hi all,

When I try to run "from nltk.book import *" get the following error message:

>>> from nltk.book import *

Type the name of the text or sentence to view it.

Do you know how to deal with it?

Thank you in advance!

Katya,

Have you used nltk.download() to download and install the "book" bundle?

The gutenberg corpus should be in nltk_data\corpora\gutenberg. I'm not sure where the extra "packages" subdirectory came from, but it's confusing the discovery algorithm.

Thank you, Alexis!

I couldn't download the 'book" with nltk.download () so I just downloaded the whole package from a different site. After I removed the subdirectory 'packages' I got a new error message, probably you know what it might be:

>>> from nltk.book import *

Thanks a lot!

It seems to be saying that you still don't have the files you think you have. There's no way to guess what could be wrong with the object you downloaded or the way you installed it, so I'd suggest you try nltk.download() again, and if necessary figure out why it's not working for you.

Thank you again! What I could find out, nltk.download () doesn't work because of proxy/firewall/etc. settings, so I was recommended either to try using cygwin (aparantly many people have this problem on Windows), or to download it from other source. So I guess, I'll have to make friends with cygwin:) Thank you very much!
