我用paddleseg训练时遇到到了同样的问题，当我使用configs/deeplabv3p/deeplabv3p_resnet50_os8_cityscapes_1024x512_80k_rmiloss.yml训练时loss也是负的，但是我用configs/deeplabv3p/deeplabv3p_resnet50_os8_cityscapes_1024x512_80k.yml训练loss就正常

I encountered the same problem, this [issue](https://github.com/TexasInstruments/edgeai-yolov5/issues/47) may help you

I‘m meeting the same problem, any solution？
