## Dataset viewer issue for '*P3*'

**Link: https://huggingface.co/datasets/bigscience/P3**

```
Status code:   400
Exception:     SplitsNotFoundError
Message:       The split names could not be parsed from the dataset config.
```
Am I the one who added this dataset ? No


Comments:
The error is now:

```
Status code:   400
Exception:     Status400Error
Message:       this dataset is not supported for now.
```

We've disabled the dataset viewer for several big datasets like this one. We hope being able to reenable it soon.

The list of splits cannot be obtained. cc @huggingface/datasets
