NLTK is a platform for building Python programs to work with human language data. In order to use it, you have to download corpora and make it available to your application. The Heroku Python buildpack has built-in support for this with the nltk.txt file.
Example nltk.txt file
wordnet
pros_cons
reuters
This will tell Heroku to automatically download these three corpora and install them into your application at build time. Make sure you have nltk specified in your Pipfile or requirements.txt!
