# Swin Transformer for Object Detection
This repo contains the supported code and configuration files to reproduce object detection results of [Swin Transformer](https://arxiv.org/pdf/2103.14030.pdf). It is based on [mmdetection](https://github.com/open-mmlab/mmdetection).

**Notes:**
- The drop path rate needs to be tuned for best practice.
- MoBY pre-trained models can be downloaded from [MoBY with Swin Transformer](https://github.com/SwinTransformer/Transformer-SSL).
## Usage
### Installation
Please refer to [get_started.md](https://github.com/open-mmlab/mmdetection/blob/master/docs/en/get_started.md) for installation and dataset preparation.
### Inference
```
# single-gpu testing
python tools/test.py --eval bbox segm
# multi-gpu testing
tools/dist_test.sh --eval bbox segm
```
### Training
To train a detector with pre-trained models, run:
```
# single-gpu training
python tools/train.py --cfg-options model.pretrained= [model.backbone.use_checkpoint=True] [other optional arguments]
# multi-gpu training
tools/dist_train.sh --cfg-options model.pretrained= [model.backbone.use_checkpoint=True] [other optional arguments]
```
For example, to train a Cascade Mask R-CNN model with a `Swin-T` backbone and 8 gpus, run:
```
tools/dist_train.sh configs/swin/cascade_mask_rcnn_swin_tiny_patch4_window7_mstrain_480-800_giou_4conv1f_adamw_3x_coco.py 8 --cfg-options model.pretrained=
```
**Note:** `use_checkpoint` is used to save GPU memory. Please refer to [this page](https://pytorch.org/docs/stable/checkpoint.html) for more details.
### Apex (optional):
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" ./
```
If you would like to disable apex, modify the type of runner as `EpochBasedRunner` and comment out the following code block in the [configuration files](configs/swin):
```
# do not use mmdet version fp16
fp16 = None
optimizer_config = dict(
type="DistOptimizerHook",
update_interval=1,
grad_clip=None,
coalesce=True,
bucket_size_mb=-1,
use_fp16=True,
)
```
