nltk NgramModel error

Question

The NgramModel class in nltk was working fine without error. However, I recently updated nltk to version 3.1 and I can no longer find the NgramModel class. When I try to import as usual:

from nltk.model import NgramModel

I get the error

ImportError: No module named 'nltk.model'.

Has NgramModel or the model module been recently replaced? is there any other process?

Answer 1

This is an open issue because of bugs.

If you're currently using the version from github, you can switch to the "model" branch, which includes the NgramModel code, though it's currently significantly behind the "develop" branch and hasn't picked up all the newest bug fixes.
