Hi 
I was trying to run a program to build a sentence tree, but the interpreter
is giving me an error such as the follows:
 
raceback (most recent call last):
  File "C:\Python22\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 301, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Grammar\grammar_pp_02.py", line 41, in ?
AttributeError: 'NoneType' object has no attribute 'draw'
 
This is what I was trying to achieve in order to build a parse tree
of the sentence in the code:
 
>>> import nltk.parser
>>> import nltk.token
>>> parser = nltk.parser.ShiftReduceParser(G)
>>> tokenizer = nltk.token.WSTokenizer()
>>> tokens = tokenizer.tokenize('the man saw a woman in the garden')
>>> parse = parser.parse(tokens)
>>> parse.draw()  <----------------even if parser module loaded
                                            it is giving me an error

Does any body know NLTK problems associated with win32 ?

thanks in advance
