ImportError: cannot import name PunktWordTokenizer

I was trying to use PunktWordTokenizer and it was occurred an error as below.

from nltk.tokenize.punkt import PunktWordTokenizer

And this gave the following error message.

Traceback (most recent call last): File "file", line 5, in <module>
from nltk.tokenize.punkt import PunktWordTokenizer ImportError: cannot import name PunktWordTokenizer

I've checked that nltk is installed and that PunkWordTokenzer is also installed using nltk.download(). Need some help for this.

Solution

  • There appears to be a regression related to PunktWordTokenizer in 3.0.2. The issue was not present in 3.0.1, rolling back to that version or earlier fixes the issue.

    >>> import nltk
>>> nltk.__version__
'3.0.2'
>>> from nltk.tokenize import PunktWordTokenizer
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name PunktWordTokenizer

    For solving this Try pip install -U nltk to upgrade your NLTK version.
