What is the Transformers Library?

The Transformers library is a machine learning library maintained by Hugging Face and the community. It provides APIs and tools to easily download and train state-of-the-art pretrained models, reducing compute costs and saving time and resources required to train a model from scratch.

The library supports a wide range of tasks across different modalities. For Natural Language Processing, it supports tasks like text classification, named entity recognition, question answering, language modeling, summarization, translation, multiple choice, and text generation. In the realm of Computer Vision, it supports image classification, object detection, and segmentation. For Audio, it supports automatic speech recognition and audio classification. It also supports Multimodal tasks like table question answering, optical character recognition, information extraction from scanned documents, video classification, and visual question answering.

The Transformers library is compatible with PyTorch, TensorFlow, and JAX, three of the most popular deep learning libraries. It provides an easy-to-use API through the pipeline() method for performing inference over a variety of tasks.

The library also provides thousands of pretrained models to perform tasks on different modalities such as text, vision, and audio. These models can be easily accessed and used with the high-level API using the pipeline function or AutoModel for more control.

In addition to the models, the Transformers library also provides almost 2000 datasets and layered APIs, allowing programmers to easily interact with those models using various libraries.

How to get started with Transformers

To get started with the Transformers library, follow these steps:

1. Installation: Install the Transformers library using pip. You also need to install your preferred machine learning framework, either PyTorch or TensorFlow. Here are the commands you need to run in your terminal:

pip install transformers
pip install torch  # For PyTorch
pip install tensorflow  # For TensorFlow

2. Understanding the Basics: The Hugging Face documentation provides a quick tour that helps you understand how to use the pipeline() for inference, load a pretrained model and preprocessor with an AutoClass, and quickly train a model with PyTorch or TensorFlow.

3. Tutorials: If you're a beginner, the tutorials section on the Hugging Face website is a great place to start. It will help you gain the basic skills you need to start using the library.

4. How-to Guides: These guides show you how to achieve specific goals, like fine-tuning a pretrained model for language modeling or how to write and share a custom model.

5. API Reference: The API reference describes all classes and functions, detailing the most important classes like configuration, models, tokenizers, and trainers.

6. Exploring Models: The Hugging Face hub provides thousands of pretrained models to perform tasks on different modalities such as text, vision, and audio. You can use the high-level API using the pipeline function or AutoModel for more control.

Remember, the Transformers library is a powerful tool that can be combined with your favorite deep learning library (PyTorch, TensorFlow, or JAX) to perform a wide range of machine learning tasks.
