Install

1. Clone this repository and navigate to STL folder

git clone https://github.com/NVlabs/STL
cd STL

2. Install Package

conda create -n STL python=3.10 -y
conda activate STL
pip install --upgrade pip
pip install -r requirements.txt

Dataset

Download ImageNet clean dataset and ImageNet-C dataset and structure the datasets as follows:

/path/to/imagenet-C/
  clean/
    class1/
      img3.jpeg
    class2/
      img4.jpeg
  corruption1/
    severity1/
      class1/
        img3.jpeg
      class2/
        img4.jpeg
    severity2/
      class1/
        img3.jpeg
      class2/
        img4.jpeg

For other out-of-distribution shift benchmarks, we use ImageNet-A or ImageNet-R for evaluation.

Pre-trained Models

FAN token labelers

Student models trained with STL (Image resolution: 224x224)

Training

STL has two phases. In the first phase, we train a FAN token labeler to produce semantically meaningful token labels. In the second phase, we train a student model by jointly using self-emerging token labels generated by FAN token labelers and original image-level labels. We provide pre-trained token labelers in Pre-trained Models. To save time, you can skip the first phase and train student models directly using the pre-trained token labelers.

Train FAN token labelers

Train FAN token labelers with a single GPU node:

python3 -m torch.distributed.launch --nproc_per_node=8 \
train_token_labeler.py /PATH/TO/IMAGENET/ --model fan_small_12_p4_hybrid_token -b 128 --sched cosine --epochs 350 \
--opt adamw -j 16 --warmup-lr 1e-6 --warmup-epochs 5 \
--model-ema-decay 0.99992 --aa rand-m9-mstd0.5-inc1 --remode pixel \
--reprob 0.3 --lr 20e-4 --min-lr 1e-6 --weight-decay .05 --drop 0.0 \
--drop-path .25 --img-size 224 --mixup 0.8 --cutmix 1.0 \
--smoothing 0.1 \
--output /PATH/TO/SAVE/CKPT/ \
--amp --model-ema \
--token-label --cls-with-single-token-label \

Train FAN token labelers with multiple GPU nodes:

CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 python3 -m torch.distributed.launch --nproc_per_node=8 --nnodes=$rank_num \
	--node_rank=$rank_index --master_addr="$ip_address" --master_port=3349 \
	train_token_labeler.py  /PATH/TO/IMAGENET/ --model fan_base_16_p4_hybrid_token -b 64 --sched cosine --epochs 350 \
	--opt adamw -j 16 --warmup-lr 1e-6 --warmup-epochs 10  \
	--model-ema-decay 0.99992 --aa rand-m9-mstd0.5-inc1 --remode pixel \
	--reprob 0.3 --lr 40e-4 --min-lr 1e-6 --weight-decay .05 --drop 0.0 \
	--drop-path .35 --img-size 224 --mixup 0.8 --cutmix 1.0 \
	--smoothing 0.1 \
	--output /PATH/TO/SAVE/CKPT/ \
	--amp --model-ema \
	--token-label --cls-with-single-token-label \

Or you can run the scripts directly:

cd scripts/fan_token_labeler/
bash fan_small_tl.sh

More details and scripts can be found in the folder scripts/fan_token_labeler/.

Train student models with STL

Train student models with STL using a single GPU node:

python3 -m torch.distributed.launch --nproc_per_node=8 \
main.py  /PATH/TO/IMAGENET/ --model fan_small_12_p4_hybrid_token -b 128 --sched cosine --epochs 350 \
--opt adamw -j 16 --warmup-lr 1e-6 --warmup-epochs 5  \
--model-ema-decay 0.99992 --aa rand-m9-mstd0.5-inc1 --remode pixel \
--reprob 0.3 --lr 20e-4 --min-lr 1e-6 --weight-decay .05 --drop 0.0 \
--drop-path .25 --img-size 224 --mixup 0.8 --cutmix 1.0 \
--smoothing 0.1 \
--output  /PATH/TO/SAVE/CKPT/ \
--amp --model-ema \
--token-label --cls-weight 1.0 --dense-weight 1.0 \

CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 python3 -m torch.distributed.launch --nproc_per_node=8 --nnodes=$rank_num \
	--node_rank=$rank_index --master_addr="$ip_address" --master_port=3349 \

Fully Attentional Networks

STL is built upon Fully Attentional Networks (FAN). FAN is a family of general-purpose Vision Transformer backbones that are highly robust to unseen natural corruptions in various visual recognition tasks. If you are interested in the original FAN design, please refer to the official implementation of FAN.
