How can't I get the Theoretical performance

[ianwang35]

I use coco dataset, and resdcn_18_512. And follow the instructions. "python train.py --log_name coco_resdcn18_512 --dataset coco --arch resdcn_18 --lr 5e-4 --lr_step 90,120 --batch_size 24 --num_epochs 100 --num_workers 8 "
After 100 epochs. I get a very poor performance. Am I missing some important steps? Thanks for everyone.

大家好，我是个新手。我使用了作者的预设指令，如上，经过100epochs后的IOU非常的低，请问我有做错哪个重要的步骤吗?感谢赐教
