an error occurs at the step ori_data, codec_data = batch

Hey expert, I have another question. When executing python train.py --conf_dir=configs/apollo.yaml, an error occurs at the step ori_data, codec_data = batch: [rank0]: ValueError: too many values to unpack (expected 2). Does this indicate any requirements for the dataset?

I think it is because your dataset's getitem does not output two items.
