Custom Backbone

Hello, I am very impressed with your work. As so, I want to train your model from scratch with different 'custom' backbone. I want to test my custom backbone with your detection strategy for my research. Hence, I want to integrate my backbone architecture to your detection system. I understand that I need to freeze BN layers, so that's ok. So, what should be the dimensions of the output of the backbone, and how can I integrate your system? I integrated my custom backbone to your demo detr model that you provide for inferencing with little changes. But, I could not find a way to integrate the backbone to your real model. I will be appreciated if you can provide tips & information, or anything that can help me. Best!
