您好，我出现和您同样的错误，请问如何解决?.data中的路径信息是正确的绝对路径。

Same problem here!

you should check coco.data and the train file in coco.data. I solved the problem by changing coco.data

@lookup1980 you are receiving this error because the dataloader is not finding any images to load in the path you provided. If you are trying to train on a custom dataset follow these directions:

Hello, I have the same mistake as you. How can I solve it? The path information in.data is the correct absolute path.
