Multiple Dataloader and source

I have multiple data loader currently and I want to read from them. I concat the data loaders but I would like to know the data comes from which original data loader so I can apply different transform to them.
Is there any way directly return the label?


Hi Thomas,

Do you have multiple dataloaders or multiple datasets? Or both?
If its datasets, you can return whatever you want from the datasets get_item() function. One idea would be to return a dataset descriptor / ID.

If its dataloaders, can you show me how you concat your loaders :)?
