A model-definition framework for state-of-the-art machine learning models across text, vision, audio, and multimodal tasks.
Transformers is a Python library that provides a unified framework for working with state-of-the-art machine learning models across text, vision, audio, and multimodal domains. It solves the problem of model definition fragmentation by offering a central, compatible definition that works with numerous training and inference frameworks, making advanced AI models accessible and easy to use.
Machine learning researchers, engineers, and developers who need to train, fine-tune, or deploy pretrained models for NLP, computer vision, audio, or multimodal tasks. It's also valuable for students and educators in AI.
Developers choose Transformers for its vast repository of pretrained models, unified API across modalities, and framework interoperability, which significantly reduces development time and computational costs compared to training models from scratch.
🤗 Transformers: the model-definition framework for state-of-the-art machine learning models in text, vision, audio, and multimodal models, for both inference and training.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Integrates with the Hugging Face Hub for access to over 1 million pretrained checkpoints across all modalities, as highlighted in the README, reducing the need to train from scratch.
Offers a high-level Pipeline class that simplifies inference for text, audio, vision, and multimodal tasks with minimal code, as shown in the quickstart examples.
Enables seamless movement of models between PyTorch, JAX, and TensorFlow, ensuring compatibility with various training and inference frameworks, as stated in the key features.
Serves as the foundation for a large community of projects and tools, with an awesome-transformers page listing 100+ projects, fostering collaboration and extensions.
The library is not designed as a toolbox of neural net components; model files lack abstractions, making it difficult to reuse parts for custom architectures, as admitted in the 'Why shouldn't I use Transformers?' section.
Optimized specifically for PyTorch models from Transformers, so for generic machine learning loops, users need to rely on other libraries like Accelerate, limiting flexibility for non-standard training workflows.
The provided examples may not work out-of-the-box for specific use cases and often need significant modification, as noted in the README, which can slow down initial experimentation.
