@PkuRainBow Thank you for your sharing! It sounds good. I will try it after refactoring of DETRs.

@Ezra-Yu Yes it is! I fixed mmdet PR. https://github.com/RistoranteRist/mmdetection/blob/yoloxpai/configs/yoloxpai/yolox_pai_s_8x8_300e_coco.py#L8

Sorry. When I pushed 'Re-request review', Collaborator reviewers were removed.

1st option looks good. I created PR for mmcv. https://github.com/open-mmlab/mmcv/pull/2278

> Are there any plans or ideas to refactor yolox_asff_pafpn.py and support todo: handle len(self.in_channels) > 3? Yes. I will implement it soon. Please wait for a few days.

@shinya7y I pushed refactored codes. Please review it.

@hhaAndroid I will try to develop based on dev-3.x. But there may not be time to contribute to mmyolo.

@Ezra-Yu Should I make this PR again for dev-1.x? Or do you plan to incorporate PRs that have been merged into dev by the mmlab team into dev-1.x as well?

Cool! Thank you for your great effort:)

@hhaAndroid I have already created PR for dev-3.x. Do you want to close this one? https://github.com/open-mmlab/mmdetection/pull/9255
