NLTK is a Python library for processing natural languages enabling easy access to “text processing libraries for classification, tokenization, stemming, tagging, parsing, and semantic reasoning, wrappers for industrial-strength NLP libraries, and an active discussion forum”.
Here’s a solution that always works:
File > Settings > Projectfrom the PyCharm menu.
- Select your current project.
- Click the
Python Interpretertab within your project tab.
- Click the small
+symbol to add a new library to the project.
- Now type in the library to be installed, in your example
"nltk"without quotes, and click
- Wait for the installation to terminate and close all popup windows.
Here’s the installation process as a short animated video—it works analogously for the NLTK library, just type in “nltk” in the search field instead:
Make sure to select only “nltk” because there are many other packages that are not required but also contain the same term (false positives):
Alternatively, you can run the
pip install nltk command in your PyCharm “Terminal” view:
$ pip install nltk
The following figure shows how to use pip to install the NLTK package:
You can check your installation using the following two lines of Python code that print out the version of the package:
import nltk print(nltk.__version__)
