vit-pytorch is a PyTorch library providing reusable implementations of the Vision Transformer and numerous related architectural variants for image classification tasks. It consolidates many attention-based vision architectures and self-supervised pre-training methods into a single installable package.
Project overview
The breadth of vision transformer architectures and pre-training tasks gathered in one library makes vit-pytorch a practical starting point for researchers and engineers who want to experiment with attention mechanisms in computer vision without re-implementing each model from scratch.

Best for
AI engineers and researchers who need PyTorch implementations of multiple vision transformer architectures for experimentation and model development.
Developers who want to integrate attention-based image classification into a local Python workflow without depending on a managed service.
Key capabilities
Provides numerous implementations of vision transformer architectures including ViT, SimpleViT, NaViT, DeepViT, CaiT, and others.
Offers built-in support for distilling knowledge from convolutional networks to vision transformers.
Includes tasks for training vision transformers using self-supervised methods like SimMIM, MAE, Masked Patch Prediction, and Masked Position Prediction.
Provides access to attention maps via forward pass modifications in specific variants.
Limitations and risks
The library does not offer pretrained models directly; users are directed to a separate repository to obtain them.
Getting started
Run pip install vit-pytorch, import ViT in a Python script, instantiate the model, and pass an image tensor to begin.
