Getting Started

You can install the required packages including: Pytorch version 1.7.1, torchvision version 0.8.2 and Timm version 0.4.8

pip install -r requirements.txt

Download and extract the ImageNet dataset. Afterwards, set the --data-path argument to the corresponding extracted ImageNet path.

Training

For training using 8 gpus, use the following command

python -m torch.distributed.launch --nproc_per_node=8 --use_env main.py --model sima_small_12_p16 --epochs 400 --batch-size 128 --drop-path 0.05 --output_dir [OUTPUT_PATH]   --data-path [DATA_PATH]
