resnet resnext 可以正常运行，但是res2net不行。求大神调bug

cpboost commented 4 years ago

需要自己写detectors的代码，

yutao007 commented 4 years ago

谢谢。我尝试的改res2net，但是自己能力不够，报上面的错误，准备等你们的改进版。

Recent Res2Net uses deep_stem instead of conv1. DetectoRS_ResNet in this repository (open-mmlab/mmdetection) looks supporting deep_stem. https://github.com/open-mmlab/mmdetection/blob/57bbfb7e275250bbf1f72f7242de2901c66b4a1c/mmdet/models/backbones/detectors_resnet.py#L290-L295
