Inquiry Regarding Contributions and Modifications in mmdet Framework

Hi GGN major contributors,

I hope this message finds you well. I am currently exploring the mmdet codebase which upon built GGN for my research. I noticed that you have created some files in the repository, like two_tower.py and pa_predictor.py and so on. I'm particularly interested in understanding if there have been any significant modifications within the existing mmdet codebase.

Could you kindly provide some insights into whether you made substantial changes directly within the framework's existing files, or if most of the modifications are contained within the files you've created?

Thank you for your time and assistance.

Best regards,
Nanxi
