STViT-R for Detection

This is an official implementation for Making Vision Transformers Efficient from A Token Sparsification View. It is based on Swin Transformer.

Notes: We will further clean the code and release the checkpoints in the future.

Usage

Installation

Please refer to MMDetection for installation and dataset preparation.

We use apex for mixed precision training by default. To install apex, run:

git clone https://github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./

Training

To train a Cascade Mask R-CNN model with a STVIT-R-Swin-S backbone and 8 gpus, run:

tools/dist_train.sh configs/swin/cascade_mask_rcnn_swin_small_patch4_window7_mstrain_480-800_giou_4conv1f_adamw_3x_coco.py 8 --cfg-options model.pretrained=<PRETRAIN_MODEL>

To train a Cascade Mask R-CNN model with a STVIT-R-Swin-B backbone and 8 gpus, run:

tools/dist_train.sh configs/swin/cascade_mask_rcnn_swin_base_patch4_window7_mstrain_480-800_giou_4conv1f_adamw_3x_coco.py 8 --cfg-options model.pretrained=<PRETRAIN_MODEL>
