Unofficial PyTorch implementation of TokenLearner by Google AI

Overview

tokenlearner-pytorch

Unofficial PyTorch implementation of TokenLearner by Ryoo et al. from Google AI (abs, pdf)

Installation

You can install TokenLearner via pip:

pip install tokenlearner-pytorch

Usage

You can access the TokenLearner class from the tokenlearner_pytorch package. You can use this layer with a Vision Transformer, MLPMixer, or Video Vision Transformer as done in the paper.

import torch
from tokenlearner_pytorch import TokenLearner

tklr = TokenLearner(S=8)
x = torch.rand(512, 32, 32, 3)
y = tklr(x) # [512, 8, 3]

You can also use TokenLearner and TokenFuser together with Multi-head Self-Attention as done in the paper:

import torch
import torch.nn as nn
from tokenlearner_pytorch import TokenLearner, TokenFuser

mhsa = nn.MultiheadAttention(3, 1)
tklr = TokenLearner(S=8)
tkfr = TokenFuser(H=32, W=32, C=3, S=8)

x = torch.rand(512, 32, 32, 3) # a batch of images

y = tklr(x)
y = y.view(8, 512, 3)
y, _ = mhsa(y, y, y) # ignore attn weights
y = y.view(512, 8, 3)

out = tkfr(y, x) # [512, 32, 23, 3]

TODO

  • Add support for temporal dimension T
  • Implement TokenFuser with ViT
  • Implement TokenFuser with ViViT
