ViViT: A Video Vision Transformer

Unofficial implementation of ViViT: A Video Vision Transformer.

Notes:

• This is the implementation of model 2 only
• Can be initialized by the original Vit pretrained weight from Google: https://storage.googleapis.com/vit_models/imagenet21k/{model_name}.npz
• Support both "Filter inflation" and "Central frame" initialization for 3Dconv
• No number for Kinetic dataset since i don't have that kind of computational power

Usage:

git clone https://github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir ./ 
pip install -r requirements.txt
wget https://storage.googleapis.com/vit_models/imagenet21k/ViT-B_16.npz
python train_vivit.py --name test_cifar --pretrained_dir /ViT-B_16.npz --dataset cifar10
