 ## Detection
-TODO: tjw
+
+We adopt yolox as the detection method. We used stronger data augmentation and ranger optimizer.
+
+### Training 
+
+Download the pretrained model at [Onedrive](https://mailstsinghuaeducn-my.sharepoint.com/personal/liuxy21_mails_tsinghua_edu_cn/_layouts/15/onedrive.aspx?ga=1&id=%2Fpersonal%2Fliuxy21%5Fmails%5Ftsinghua%5Fedu%5Fcn%2FDocuments%2Fbop%5Fchallenge%5F2022%2Fpretraied%5Fmodels%2Fyolox) (password: groupji) and put it in the folder `pretrained_models/yolox`. Then use the following command:
+
+`./det/yolox/tools/train_yolox.sh <config_path> <gpu_ids> (other args)`
+
+### Testing 
+
+`./det/yolox/tools/test_yolox.sh <config_path> <gpu_ids> <ckpt_path> (other args)`
