Transformers
Overview
The Hugging Face Transformers library provides access to thousands of pre-trained models for tasks across NLP, computer vision, audio, and multimodal domains. Use this skill to load models, perform inference, and fine-tune on custom data.
Installation
Tested against transformers 5.12.0 (current PyPI release; June 2026). Requires Python 3.10+; the torch extra currently requires PyTorch 2.4+.
uv pip install "transformers[torch]==5.12.0" huggingface_hub==1.19.0 datasets==5.0.0 evaluate==0.4.6 accelerate==1.14.0
For vision tasks, add:
uv pip install timm==1.0.27 pillow==12.2.0
For audio tasks, add:
uv pip install librosa==0.11.0 soundfile==0.14.0
These pins are for reproducible examples. For exploratory work, loosen them only after checking the Transformers and Hub release notes for API changes.
Check your version:
import transformers
print(transformers.__version__)
Authentication
Many models on the Hugging Face Hub are gated or private. Authenticate before loading them.
Recommended: CLI login (stores token in ~/.cache/huggingface/token):
