NLTK Lookup Error

Question

While running a Python script using NLTK I got this:

Traceback (most recent call last):
  File \"cpicklesave.py\", line 56, in 
    pos = nltk.         


        

Answer 1

TL;DR

import nltk
nltk.download('averaged_perceptron_tagger')

Or to download all packages + data + docs:

import nltk
nltk.download('all')

See How do I download NLTK data?
