Help for backbone

Hello, thanks for the share, I got lots of help from the program, but I need to change the result of point position, so I need to train a new model to fit it, could I got the information fo backbone, thanks so much.

The issue asks for information on the backbone to train a new model. Look at the model architecture in the repository, likely in models/ or network/ directories. Check documentation or examples for training procedures. Understanding the existing backbone and training pipeline is needed before any changes.
