""" Vision Transformer (ViT) in PyTorch

A PyTorch implement of Vision Transformers as described in:

'An Image Is Worth 16 x 16 Words: Transformers for Image Recognition at Scale'
    - https://arxiv.org/abs/2010.11929

`How to train your ViT? Data, Augmentation, and Regularization in Vision Transformers`
    - https://arxiv.org/abs/2106.10270

`FlexiViT: One Model for All Patch Sizes`
    - https://arxiv.org/abs/2212.08013

The official jax code is released and available at
  * https://github.com/google-research/vision_transformer
