bad result from Image Demo Segmentation

[YicanGgg]

我用ADE20K CUDA_VISIBLE_DEVICES=0 python image_demo.py
datapics/demo.jpg
configs/ade20k/upernet_internimage_t_512_160k_ade20k.py
checkpoint_dir/seg/upernet_internimage_t_512_160k_ade20k.pth
--palette ade20k

得到的结果非常好,

但是当我用cityscapes结果非常差, CUDA_VISIBLE_DEVICES=0 python image_demo.py
datapics/demo.jpg
configs/cityscapes/upernet_internimage_xl_512x1024_160k_mapillary2cityscapes.py
checkpoint_dir/upernet_internimage_xl_512x1024_160k_mapillary2cityscapes.pth
--palette cityscapes

这是什么原因呢
