The Token Classification repository template is designed to help you start your token classification project using the Hugging Face Hub’s Inference API. This guide will walk you through the necessary steps to set up and implement your project. Let’s dive into the mechanics of setting up a robust token classification pipeline!

Step 1: Specify Requirements

The first step in our journey is to define the requirements for your project. This is done by creating a requirements.txt file. This file will list all the dependencies needed for your project to run smoothly.

Step 2: Implement the Pipeline

Next, we need to work on two critical methods in the pipeline.py file:

• __init__ Method: This method is your project’s constructor. Think of it like a chef preparing all the ingredients before cooking a meal. Here, you will load the model and preload elements essential for inference, such as processors and tokenizers. This method is executed only once when your application starts.
• __call__ Method: Now, this is where the magic happens! This method is invoked every time an inference is made. You can visualize it as the chef actually cooking the meal—the recipe you provide will dictate the outcome!

Make sure your input and output specifications align with what is defined in the template for the pipeline to function correctly.

# Example of defining the __init__ and __call__ methods
class TokenClassificationPipeline:
    def __init__(self):
        # Load model, processors, tokenizers
        pass

    def __call__(self, input_data):
        # Perform inference
        pass

How to Create Your Repository

Follow these steps to create a repository and push your work to the Hugging Face Hub:

1. First, create a new repository at Hugging Face.
2. Clone the template repository using the command:

git clone https://huggingface.co/template/token-classification

3. Navigate into your cloned directory:

cd token-classification

4. Set the remote URL for your repository:

git remote set-url origin https://huggingface.co/$YOUR_USER/$YOUR_REPO_NAME

5. Finally, push your changes to the repository:

git push --force

Troubleshooting

If you encounter any issues, here are some troubleshooting tips:

• Ensure that all dependencies in your requirements.txt file are correctly specified.
• Double-check that your input/output specifications match what is defined in the template.
• If you run into model-loading errors, verify the model’s availability on Hugging Face Hub.
