Hi!

Congrats on this amazing library.

I am uploading a dataset programmatically using `push_to_hub` and defining the features as follows:

```auto
# ds contains text and label strings
hf_ds = Dataset.from_dict(
    ds,
    features=Features({
        "text": Value("string"),
        "label": ClassLabel(names=['World', 'Sports', ..])
    })
)
hf_ds.push_to_hub("Recognai/corrected_labels_ag_news")

```

The thing is that even if I see the ClassLabel feature when I do `hf_ds.features`. The result on the dataset preview shows the labels as `int` and seems to indicate they’ve been given the `int` type.

Is there something I’m doing wrong on my side?

For reference this is the dataset: [Recognai/corrected\_labels\_ag\_news · Datasets at Hugging Face](https://huggingface.co/datasets/Recognai/corrected_labels_ag_news)

Sorry I’ve seen this has already been tackled here:

> <https://github.com/huggingface/datasets/pull/3467>
>
> When doing \`push\_to\_hub\`, the feature types are lost (see issue https://github.c…om/huggingface/datasets/issues/3394).
> This PR fixes this by also pushing a \`dataset\_infos.json\` file to the Hub, that stores the feature types.
> 
> Other minor changes:
> \- renamed the \`\_\_\_\` separator to \`--\`, since \`--\` is now disallowed in a name in the back-end.
> 
> I tested this feature with datasets like conll2003 that has feature types like \`ClassLabel\` that were previously lost.
> 
> Close https://github.com/huggingface/datasets/issues/3394
> 
> I would like to include this in today's release (though not mandatory), so feel free to comment/suggest changes
