About v3 anchor-free methods

[Apostatee]

I looked through your codes and I have no idea where this anchor generation module is and how to change default anchor size according to my training data ? It seems like you directly compute location loss only using gtbox and network predictions ? When in test mode, I wonder if it directly outputs the coordinates rather than offsets(associate with each anchor) ?

@Apostatee output offsets when testing.

Thanks ! Performance is great on my own data
