| You should be familiar with how to write a training loop from the [MNIST Example](https://flax.readthedocs.io/en/stable/mnist_tutorial.html). For this tutorial, we'll use a dummy training step that takes in 4-D image arrays and 1-D label vectors. Our goal in data loading will be to create these tensors, implementing the `get_batches` generator below. | ||

can we add this as a docs dependency instead?

Maybe we could recommend jax.dlpack.from_dlpack here?

could be good to recreate splits again in this section to make it a bit more self contained.

This PR ports the Jax AI stack DataLoader tutorial to the flax docs. I've completely rewritten the tutorial, however, to focus entirely on dataloaders, leaving the model creation and jax transformations to other tutorials. This is part of the workstream outlined in #5433
