In this video I implement the Vision Transformer from scratch. It is very much a clone of the implementation provided in https://github.com/rwightman/pytorch-.... I focus solely on the architecture and inference and do not talk about training. I discuss all the relevant concepts that the Vision Transformer is using e.g. patch embedding, attention mechanism, layer normalization and many others.

My implementation: https://github.com/jankrepl/mildlyove...
timm implementation: https://github.com/rwightman/pytorch-...
lucidrains implementation: https://github.com/lucidrains/vit-pyt...
