from nltk.util import Trie ImportError: cannot import name Trie

I am new in NLP (Natural Language Processing), I have installed NLTK on my computer and I have downloaded all the packages using nltk.download()

My Script

from nltk.tokenize import sent_tokenize

example_text = "Hello Mr. Shan, how are you doing? the weather is quite cool today in Guwahati. I heard you are going to Delhi tomorrow."

print(sent_tokenize(example_text))

Error

C:\wamp64\www\python\NLTK>python test.py

I can see that your script is named test.py, but I'm wondering if at any point you created a tokenize.py file? Try removing any tokenize.pyc and renaming any tokenize.py file. I had this same issue just now. Upon renaming the file it worked.

Also note that you will have to import nltk before being able to call from nltk.
