MIOU effect on the dataset

[KrisLi]

Hello Author.
I use resnet101 as the backbone of the network and use it to train on cityscapes dataset, the miu metric I get is only 73.4, which is much worse than the 76.2 you mentioned. Is there something wrong with me?
The following is my training code.

python main.py --model deeplabv3plus_resnet101 --dataset cityscapes --enable_vis --vis_port 28333 --gpu_id 0,1 --lr 0.1 --crop_size 768 --batch_size 16 --output_stride 16 --data_root ./datasets/data/cityscapes
