Natural Language Processing with Python .dispersion_plot returns nothing

2013-06-17 Thread sixtyfourbit 
I'm in the first chapter of Natural Language Processing with Python and am 
trying to run the example .dispersion_plot. I am using Python 2.7.4 (Anaconda) 
on Mac OSX 10.8.

When I load all of the necessary modules and try to create the dispersion 
plott, I get no return - no plot, no error message, not even a new >>> prompt, 
just a blinking cursor under the last line I typed. Here is what I've been 
doing:

[~]:  python
Python 2.7.4 |Anaconda 1.5.1 (x86_64)| (default, May  9 2013, 12:12:00) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> import matplotlib
>>> import nltk
>>> from nltk.book import *
*** Introductory Examples for the NLTK Book ***
Loading text1, ..., text9 and sent1, ..., sent9
Type the name of the text or sentence to view it.
Type: 'texts()' or 'sents()' to list the materials.
text1: Moby Dick by Herman Melville 1851
text2: Sense and Sensibility by Jane Austen 1811
text3: The Book of Genesis
text4: Inaugural Address Corpus
text5: Chat Corpus
text6: Monty Python and the Holy Grail
text7: Wall Street Journal
text8: Personals Corpus
text9: The Man Who Was Thursday by G . K . Chesterton 1908
>>> text4.dispersion_plot(["citizens", "democracy", "freedom", "duties", 
>>> "America"])

...and nothing. I can't paste it but my cursor is just blinking under my last 
command with no prompt. So far the other example commands from the chapter 
(e.g. .concordance) work fine, so I'm guessing the problem is something with 
numpy or matplotlib. I had a heck of a time getting matplotlib installed 
correctly (kept getting errors saying that it wasn't installed even when I had 
installed it), but since switching to the Anaconda distro, which had those 
prepackaged, I haven't gotten any module errors.

Any advice??

I let it run for 5-10 minutes.  It's doing this no matter which text I try to 
run the dispersion plot on
