IOError: brown is not installed

[enas khalil]

hello ,

when i run this code for unigramtagger :

 

from nltk.tagger import *
from nltk.corpus import brown
    # Tokenize ten texts from the Brown Corpus
train_tokens = []
for item in brown.items()[:10]:
    train_tokens.append(brown.read(item))
    # Initialise and train a unigram tagger
mytagger = UnigramTagger(SUBTOKENS='WORDS')
for tok in train_tokens: mytagger.train(tok)

#Once a UnigramTagger has been trained, the tag() method can be used to tag new text: 
text_token = Token(TEXT="John saw the book on the table")
WhitespaceTokenizer(SUBTOKENS='WORDS').tokenize(text_token)
mytagger.tag(text_token)
print text_token

 

i got the following :

 

Traceback (most recent call last):
  File "F:\MSC first Chapters\unigramgtag1.py", line 5, in -toplevel-
    for item in brown.items()[:10]:
  File "C:\Python24\Lib\site-packages\nltk\corpus\__init__.py", line 589, in items
    self._initialize()
  File "C:\Python24\Lib\site-packages\nltk\corpus\__init__.py", line 518, in _initialize
    raise IOError('%s is not installed' % self._name)


IOError: brown is not installed

 

although i have extracted the brown folder and put it in the NLTK path 

 

what should i do 

thanks in advance
