About using custom detectors in mmtracking

[vickyyd]

Hi, mmtracking has done an outstanding job. I have already developed a custom detector in mmdetection, and I would like to know how to introduce the developed custom detector into mmtracking. To make it clear, here is an example of introducing custom Necks. I have already set up the corresponding settings in mmdet/models/necks, if I were to introduce them into mmtracking,

1. I need to complete the setup in mmtrack/models/necks and modify the files mmtrack/models/init.py and mmtrack/models/builder.py.
2. Copy mmdet/models/necks and related files from mmdetection to the mmtracking root directory. Should I do operation 1 or operation 2, or do I need to do something else. Thank you.

Hi，the Necks in mmdet/models/necks you can use it free in mmtracking and don't need to complete it or copy it in mmtracking if you don't do any changes about it. In this case, you can refer to FPN neck.

If you want to do some changes on the Neck from mmdetection, you should do the operation 1, but you can also borrow some code about Neck in mmdetection.
