Re: [nltk-users] Help! nltk.data.load error

[Richard Careaga]

Try

grammar1 = nltk.data.load('/users/luke/mygrammar.cfg') if you are using *nix and 'luke' is your home directory and mygrammar.cfg is in that directory, or it's Win equivalent.

Hi:

I have the following error message when I try to load a .cfg file. I
used the following expression.

  

grammar1 = nltk.data.load('file:mygrammar.cfg')
    

The actual error message is as follows. Could anyone help me out?
Thanks much in advance.

  

Traceback (most recent call last):

The original error message suggests that the file was found, but that
its content is not in the right format.
This suggested fix looks like it is for a different error (file not found).

Luke: can you show us the first few lines of your grammar file?

Steven:

Thanks very much for your message.

Actually, I made a mistake. Originally, I included "grammar1 = nltk.parse.cfg(""" ... """)" in "mygrammar.cfg". Later I noticed that it should not be part of the .cfg file. After removing this part, the file loads correctly.

Indeed, the error message was right. The content was not in the right format. Thanks again!
