Folks,
I am trying to run a simple example associated with nltk.
I get some error and I don't know what the issue is.
I need some guidance please.
I am using python canopy distribution
The following is the code:
inputstring = ' This is an example sent. The sentence splitter will split on
sent markers. Ohh really !!'
from nltk.tokenize import sent_tokenize
sentences = sent_tokenize(inputstring)
print sentences
The following is the error report:
