I am trying to load conll2003 dataset the basic way I learned like this

```auto
from datasets import load_dataset
dataset = load_dataset("conll2003")

```

but I am running into this error

```auto

Could someone tell me what is wrong?

Try:

```py
from datasets import load_dataset
dataset = load_dataset("lhoestq/conll2003")

```

This is because [support for `trust_remote_code=True` was removed in `datasets` library version 4.0.0 and later](https://github.com/huggingface/datasets/releases/tag/4.0.0). You can work around this by using datasets that don’t rely on builder scripts (like the one shown above) or by downgrading the `datasets` library to version 3.6.0 or earlier.

That works, thank you.  
That’s interesting, so I assume the support for loading scripts has also been removed, so if I want to upload a custom dataset, I will need to manually convert it into DatasetDict and push it using this class.
