The mAP of SSD-Resnet is lower than SSD-VGG16.

Thanks for your work !
I just replace the backbone of SSD with 'torchvision.models.resnet', but the mAP becomes lower than the VGG-16. The results are follow:

backbone	mAP
VGG-16	69.13
Res-50	67.8
Res-18	63.76
Mobile-V2	62.12

Could you provide some help ?

It would be great if you add the code of the SSD-Resnet to this project.

Thanks a million for your help !

#我想问一下大家在训练的过程有碰到AP为0的情况吗，我是用的自己的数据集训练的。
