我把SSDD的数据集转换成了coco的格式，然后跑你的代码出现了这个问题，请问怎么解决？

Hi~
Our code is based on Detectron2, the way of using custom dataset is the same as detectron2, I guess you could refer to Use Custom Dataset.

@18456432930 你解决了这个问题吗？

It seems you still use 'coco_2017_train' as your dataset name in your config file, you can try to register your dataset use register_coco_instances with from detectron2.data.datasets import register_coco_instances to see if you can solve your question? If not, you should rewrite your register follow register_coco_instances

Can you please explain in detail which file should be modified? Thank you very much!

in your train_net.py is ok, add sth like this
