Is it possible to write custom dataloader and embed it in the architecture of the QuartzNet model for training?

[psydok]

Good evening! I have 2 questions...

1. Is it possible to write your own dataloader and embed it in the architecture of the QuartzNet model for training?
   It seems to me that I saw somewhere how the default dataloader is replaced with a custom dataloader. But I can't find an example of how to do it.
2. Is it possible to somehow see which dataloader is used from the loaded model in the code?

Many thanks in advance for any insights!

You can potentially create your own dataloader and pass it to trainer.fit(). See the lightning documention for such use case, but note that we have never tried it.

You can access model._train_dl, _validation_dl and _test_dl I think for most Nemo models.
