Unlocking the Power of Hugging Face Tokens: A Comprehensive Guide

How to Use Hugging Face Tokens: Step-by-Step Guide for Beginners

Hugging Face Tokens offer developers a quick and efficient way to handle tokenization. It helps in transforming natural human language sentences into machine-understandable sequences of numeric or alphanumeric symbols. The process is crucial for Machine Learning models because they can easily tokenize large amounts of text data into small units that can be processed faster during training and inference.

If you are new to Hugging Face Tokens or tokenization as a whole, this step-by-step guide will walk you through how to use Hugging Face Tokens effectively:

Step 1: Install the Required Libraries

The first thing you need to do is install the necessary libraries for tokenization. You can easily do that by running the following command on your terminal:

“`
pip install transformers==4.2.2
“`

Step 2: Importing the required classes

Now that we have installed the required libraries, we need to import some classes from them. In this guide, we will be using two classes; Tokenizer and PreTrainedTokenizerFast.

Open your favorite text editor, create a new python file and paste the following code snippet:

“`
from transformers import PreTrainedTokenizerFast, Tokenizer
tokenizer = Tokenizer(PreTrainedTokenizerFast.from_pretrained(‘bert-base-uncased’))
“`

This code initializes the tokenizer object with PreTrainedTokenizerFast from BERT-base model.

Step 3: Encode Text Using Hugging Face Tokens

To encode text using Hugging Face tokens, pass it as a parameter to tokenizer.encode function:

“`
text_to_tokenize = “I love natural language processing”
encoded_text = tokenizer.encode(text_to_tokenize)
print(encoded_text)
“`

The output should be numerical sequence encoded by transformer library.

Step 4: Decode Text Using Hugging Face Tokens

To decode a numerical sequence generated using tokenizer.encode method back to original sentence form use tokenizer.decode function as follows:

“`
decoded_text = tokenizer.decode(encoded_text)
print(decoded_text)
“`

The output should be “I love natural language processing.”

Step 5: Tokenize Multiple Sentences

You can also tokenize multiple sentences by changing line separator instead of the whitespace using the following code snippet:

“`
text_to_tokenize = “I love natural language processingnMy favorite deep learning model is Transformer”
encoded_text = tokenizer.encode(text_to_tokenize)
print(encoded_text)
“`

It will output numerical representation of these two sentences on separate lines.

Step 6: Use Tokenizer with Regular Expressions (Regex)

Hugging Face Tokens come with powerful features and one of them is Regex. It’s useful when you want to preprocess text data before tokenization. Here’s an example:

“`
import re
text_to_tokenize = “””
John visited United States Of America last year.
Canada is known for its maple syrup.
“””

# Replace all non-alphabetic characters and symbols with a space character.
text_without_punctuation_and_symbols = re.sub(‘[^a-zA-zs]’, ”, text_to_tokenize)

# Tokenize using Hugging Face Tokens’ PreTrainedTokenizerFast with lowercase option turned on by default.
encoded_text = tokenizer.encode(text_without_punctuation_and_symbols.lower())
print(f”Encoded Text: {encoded_text}”)
decoded_text = tokenizer.decode(encoded_text, clean_up_tokenization_spaces=True)
print(f”Decoded Text: {decoded_text}”)
“`

This code replaces all non-alphabetic characters and symbols in text_with_punctuation_and_symbols variable and then passes it as a parameter to tokenizer.encode method. encoded_text’s sequence generated this way can later be decoded back to English sentence form using tokenizer.decode method.

Now that you have learned how to use Hugging Face Tokens step-by-step, we hope you find it useful in your future projects involving machine learning models that deal with human language data!
