  • My guess is that `resource_name.split('/')` returns a list of a single element, and you're trying to access element 2 (index 1). The `resource_name` probably doesn't have the `'/'` character. – Ted Klein Bergman May 11 '19 at 09:23
  • The library seems to expect something with a `/` as the argument. – Klaus D. May 11 '19 at 09:27
  • The argument to `nltk.data.find()` is supposed to be a pathname to the file containing the corpus, not just a filename. – Barmar May 11 '19 at 09:28
  • See the examples [here](http://www.nltk.org/howto/data.html) – Barmar May 11 '19 at 09:28
  • I have watched a tutorial and the instructor was getting the list of files in the corpora with the exact same line of code – Pawan May 11 '19 at 09:36

TL;DR

You have to first download the corpora.

>>> import os
>>> import nltk
>>> nltk.download('popular')
>>> print(os.listdir(nltk.data.find("corpora")))

But the printing of what's inside the corpora directory don't help much, maybe hints from this would be more helpful: https://stackoverflow.com/a/30822962/610569

You need to add 'from future import print_function' to your code, so use the following:

from __future__ import print_function
import os
import nltk
import nltk.corpus
nltk.download('popular')
print(os.listdir(nltk.data.find("corpora")))

you have to Download the Data first.

See: https://www.nltk.org/data.html

Import nltk library and downlowd the dataset you need:

import nltk
nltk.download()

To test that the data has been installed:

from nltk.corpus import brown
print(", ".join(brown.words()))

Here assumes you downloaded the Brown Corpus. See a list of the available corpus here: https://www.nltk.org/nltk_data/
