How to make a infinite dataloader with shuffle with huggingface datasets

🤗Datasets

Hi,
I have a huggingface dataset and I want to make a dataloader from it, which is 1) infinite 2) shuffles the data. I tried with this version, but this does not work with accelerator, and making the infinite loop with generator loop, accerelator does not modify the types automatically. How should I write this?

 dataloader = DataLoader(
        dataset,
        batch_size=batch_size,
        collate_fn=data_collator,
        num_workers=data_args.dataloader_num_workers,
        pin_memory=True)
 
    while True:
            for batch in dataloader:
                yield batch

thanks @lhoestq for any suggestion on this.

What happens exactly with the accelerator ?
