About DDP #172

Closed Someone-sleeping closed 8 months ago

Someone-sleeping commented 1 year ago

I have trained my model using DDP, but I am unable to achieve the mentioned mIoU 76.1 on the NuScenes dataset. I am wondering if using DDP has negatively affected the model's performance.

envs: spconv 2.3.5 torch 1.10.1+cu113
