mmdet pretrained model warning

[Jasookii]

When I used the mmdet framework, I set the parameter model.pretrained to a pretrained model of timm DaViT-T, which would lead to the above problems. By printing the two models, I found that there were some differences between them.Is there something wrong with how I use it.

I found that timm's pretrained model had a classification head, while mmdet's backbone did not. So what was the correct setting for model. pretrained?
