Method Description :
Our method is based on the ResNet and ResNet variants, ResNet101,ResNet152[1], ResNext101[2] and ResNest101[3].
Due to limited resources, we use fp16, part of training samples and less training epochs to speed up.
We totaly trained 8 models. In the test stage, we use multi-scale,multi-crop and multi-model fusion.
