what’s wrong with this data_loder?

It seems you might be using a 3rd party DataLoader implementation defined in pytorch-deeplab-xception/dataloaders/__init__.py, which raises the NotImplementedError, so should check this file and make sure this class is used as expected.

PS: you can post code snippets by wrapping them into three backticks ```, which makes debugging easier. :wink:

Thanks a lot.

It’s this one, but why the data can not loaded in?

Could you post an executable code snippet, so that we could take a look, please?
