How to download the NLTK library?

This recipe helps you download the NLTK library.

Recipe Objective: How to download the NLTK library?

This step-by-step recipe will show you how to download NLTK in Jupyter Notebook and how to download Specific packages from the NLTK library.

How To Download NLTK in Jupyter Notebook?

The below steps will help you install and download the NLTK library in Jupter Notebook.

Step 1 - Install the NLTK in Jupyter Notebook Using pip command

pip install nltk

If it is already installed or present in your notebook, it will prompt Requirement already Satisfied; otherwise, it will start downloading and installing the NLTK library in your notebook

Step 2 - How to Import NLTK in Python

This step will show you how to import NLTK in Jupyter Notebook.

import nltk

By using the above command, you can import the nltk library for your further operations.

Step 3 - Installing All from NLTK library

nltk.download('all')

If we want to download all packages from the NLTk library, then by using the above command, we can download the packages that will unzip all the packages from NLTK Corpus, for example, Stemmer, lemmatizer, and many more.

Step 4 - Downloading lemmatizers from NLTK

nltk.download('wordnet') from nltk.stem import WordNetLemmatizerd

You can use the above command to download WordNet Lemmatizer from the NLTK library and import it for further operations.

Step 5 - How To Download NLTK Stopwords

nltk.download('stopwords')

By using the above command, we will be able to download stopwords from the NLTK library.

How to Use NLTK in Jupyter Notebook?

Here is an example to show you how to NLTK in Jupyter Notebook to remove stopwords from text-

import nltk

def remove_stopwords(text):

  stop_words = nltk.corpus.stopwords.words('english')

  filtered_text = [word for word in text.split() if word not in stop_words]

  return filtered_text

text = "This is a sentence with some stopwords."

filtered_text = remove_stopwords(text)

print(filtered_text)

How to Install NLTK in Visual Studio Code?

You can install NLTK in VS Code using the following steps-

  1. Open Visual Studio Code.

  2. Click on the Extensions icon in the left sidebar.

  3. Search for "Python" and install the "Python" extension.

  4. Open a new file and create a Python script.

  5. Import the NLTK library:

import nltk

  1. Use the nltk.download() function to download the NLTK data:

nltk.download('all')

This will download all the NLTK data, which is about 1.5 GB.

FAQs

  1. How do I install NLTK using pip?
