No module named 'corpora'

This error typically occurs when you are trying to import the "corpora" module in Python, but the module is not installed on your system.

To resolve this error, you need to install the "nltk" package which includes the "corpora" module. You can install it using pip by running the following command in your terminal or command prompt:

pip install nltk

Once the installation is complete, you can import the "corpora" module in your Python code without any errors.

Here is an example of how to import and use the "corpora" module to access the "gutenberg" corpus:

import nltk

nltk.download('gutenberg')   # download the gutenberg corpus

from nltk.corpus import gutenberg

# access the text of the first book in the gutenberg corpus
emma = gutenberg.words('austen-emma.txt')
