Hello,when i run the train_coco.py,i came across a bug:'AttributeError: 'Trainer' object has no attribute '_detect_anomaly',could you help me?

Hi, this problem is caused by the APEX library. We have recently updated the whole repository, and you do not need APEX any more.

visdrone training is pulling and doing coco dataset training

Hi, please try [train_visdrone.py](https://github.com/ChenhongyiYang/QueryDet-PyTorch/blob/main/train_visdrone.py) for VisDrone experiments.

loss nan!

Hi, we have recently updated a new VisDrone training config (gradient clip added), which can avoid NaN now.

Can anyone successfully run this project, please tell me your versions, thx

Hi, we have recently updated the whole repository to support newer versions of PyTorch, Detectron2, and Spconv. Now, you can set up your environment by running the sample setup script...

Cannot achieve good accuracy after training on COCO dataset

Hi, is this the baseline RetinaNet model? We used the default setting for RetinaNet provided by Detectron2 and the final AP should be around 37.3. We recommend you first try...

PGD for coupled head?

Hi, thank you for being interested in our paper. We do not really need a spatial attention mask for regression because the regression loss is only applied to foreground areas....

About top-K highest quality score?

Hi. Yes, for each GT, the TopK is computed from all feature points across all feature levels, although in most cases those topk points will generated by the same feature...

''Non-existent config key: META_INFO.EVAL_SMALL_CLS''

Hi, may I ask if you are using the latest code?

dataset path

Hey, you can set you dataset path following https://github.com/ChenhongyiYang/QueryDet-PyTorch/blob/afc2a9f5aa89a6b4dd2bb6f5d2da9bab1dc46f6b/configs/custom_config.py#L73. For COCO, please refer to the detectron2 documents for dataset setting.
