<sup>Originally posted by **RitchieP** April  1, 2024</sup>
Currently, I have a dataset hosted on Huggingface with a custom script [here](https://huggingface.co/datasets/RitchieP/VerbaLex_voice).

I'm loading my dataset as below.
```py
from datasets import load_dataset, IterableDatasetDict

dataset = IterableDatasetDict()

dataset["train"] = load_dataset("RitchieP/VerbaLex_voice", "ar", split="train", use_auth_token=True, streaming=True)
dataset["test"] = load_dataset("RitchieP/VerbaLex_voice", "ar", split="test", use_auth_token=True, streaming=True)
```

And when I try to see the data I have loaded with
```py
list(dataset["train"].take(1))
```

And it gives me this stack trace
```

```
After looking into the stack trace, and referring to the source codes, it looks like its trying to access a directory in the notebook's environment and I don't understand why.

Not sure if its a bug in Datasets library, so I'm opening a discussions first. Feel free to ask for more information if needed. Appreciate any help in advance!</div>

Hi, referring to the discussion title above, after further digging, I think it's an issue within the datasets library. But not quite sure where it is. 

If you require any more info or actions from me, please let me know. Appreciate any help in advance!
