Why can't I import nltk?

On windows with 64-bit OS after installing nltk-2.0.4.win-amd64-py2.7.exe from http://www.lfd.uci.edu/~gohlke/pythonlibs/ for my 64-bit python, I launched "import nltk" to get the following error!

Traceback (most recent call last):
  File "<pyshell#25>", line 1, in <module>
    import nltk
  File "C:\Python27\lib\site-packages\nltk\__init__.py", line 131, in <module>

    from nltk import tokenize, tree
ImportError: cannot import name tokenize

Suggestions on how to fix this will be greatly appreciated. Thanks

I solve this problem as following link. It seems that the Python installer sometimes cannot create the correct registry entries in Win7, users need to manually create them.
