关于精度和训练问题

Open sxhxliang opened this issue 4 years ago • 4 comments

readme 里的37的精度是 2x 的训练结果?还有4 GPU 的精度是多少,我看跑了官方的源码resnet50 4GPU训练1x 有38+的精度

这个代码目前没有在1x达到37的精度(包括之前按照论文配置的复现),可能是resize问题或者忽略了一些trick。

4GPU应该差不多,因为BN是冻结的,梯度累加应该不影响结果

Is it because of SyncBatchNorm? Commonly SyncBatchNorm can give about 1mAP improvements.

I've nealy reached paper accureacy at 1x. Please see https://github.com/xytpai/DetX-FCOS
