Unable to load AutoTrain-generated dataset from the hub
### Describe the bug

### Steps to reproduce the bug

Steps to reproduce:

1. `pip install datasets==2.10.1`
2. Attempt to load (private dataset). Note that I'm authenticated via ` huggingface-cli login`


```
from datasets import load_dataset

# load dataset
dataset = "ijmiller2/autotrain-data-betterbin-vision-10000"
dataset = load_dataset(dataset)
```

Here's the full traceback:

### Expected behavior

I'm ultimately trying to generate my own performance metrics on validation data (before putting an endpoint into production) and so was hoping to load all or at least the validation subset from the hub. 

I'm expecting the `load_dataset()` function to work as shown in the documentation [here](https://huggingface.co/docs/datasets/loading#hugging-face-hub):

```python
dataset = load_dataset(
  "lhoestq/custom_squad",
  revision="main"  # tag name, or branch name, or commit hash
)
```

### Environment info

- `datasets` version: 2.10.1
- Platform: macOS-13.2.1-arm64-arm-64bit
- Python version: 3.8.13
- PyArrow version: 9.0.0
- Pandas version: 1.4.4
The AutoTrain format is not supported right now. I think it would require a dedicated dataset builder Okay, good to know. Thanks for the reply. For now I will just have to
manage the split manually before training, because I can’t find any way of
pulling out file indices or file names from the autogenerated split. The
file names field of the image dataset (loaded directly from arrow file) is
missing, just fyi (for anyone else this might be relevant too).
