IndexError: Invalid key is out of bounds for size 0 despite having a populated dataset
State: closed

### Describe the bug

I am encountering an `IndexError` when trying to access data from a DataLoader which wraps around a dataset I've loaded using the `datasets` library. The error suggests that the dataset size is `0`, but when I check the length and print the dataset, it's clear that it has `1166` entries.

### Steps to reproduce the bug

1. Load a dataset with `1166` entries.
2. Create a DataLoader using this dataset.
3. Try iterating over the DataLoader.

code:
```python
def get_train_dataloader(self) -> DataLoader:
        if self.train_dataset is None:
            raise ValueError("Trainer: training requires a train_dataset.")

        train_dataset = self.train_dataset
        data_collator = self.data_collator
        print(len(train_dataset))
        print(train_dataset)
        if is_datasets_available() and isinstance(train_dataset, datasets.Dataset):
            train_dataset = self._remove_unused_columns(train_dataset, description="training")
        else:
            data_collator = self._get_collator_with_removed_columns(data_collator, description="training")
        train_sampler = self._get_train_sampler()
        dl = DataLoader(
            train_dataset,
            batch_size=self._train_batch_size,
            sampler=train_sampler,
            collate_fn=data_collator,
            drop_last=self.args.dataloader_drop_last,
            num_workers=self.args.dataloader_num_workers,
            pin_memory=self.args.dataloader_pin_memory,
            worker_init_fn=seed_worker,
        )
        print(dl)
        print(len(dl))
        for i in dl:
            print(i)
            break
        return dl
```

output : 
```
1166
Dataset({
    features: ['input_ids', 'special_tokens_mask'],
    num_rows: 1166
})
<torch.utils.data.dataloader.DataLoader object ...>
146
```
Error:

### Expected behavior

I expect to be able to iterate over the DataLoader without encountering an IndexError since the dataset is populated.
