I created a DatasetDict and pushed it [here](https://huggingface.co/datasets/dansbecker/hackernews_hiring_posts).
I’m getting the message
```auto
Server Error
Status code: 400
Exception: Status400Error
Message: could not get the config name for this dataset
```
Am I supposed to create a config file somewhere that I missed so the dataset viewer works?
Thanks!

Hey @dansbecker as far as I know, the dataset viewer currently supports datasets with a loading script ([example](https://huggingface.co/datasets/GEM/squad_v2/blob/main/squad_v2.py)) or raw data files in common formats like JSON and CSV ([example](https://huggingface.co/datasets/transformersbook/codeparrot-valid)).
I agree that being able view the contents of `DatasetDict` objects would be a nice feature, so I’m tagging @lhoestq and @severo in case they have any additional insights here 🙂

Hi ! Please use `my_dataset.push_to_hub()` to save your dataset on the Hub. Then to reload you can use `load_dataset()`. You can see the documentation [here](https://huggingface.co/docs/datasets/upload_dataset.html#upload-from-python)
Datasets saved with `save_to_disk` and uploaded manually to the Hub are not supported (yet). This is because saving locally uses the Arrow format: while this format allows a dataset to be immediately reloaded, it’s not the preferred format to store in the cloud since it’s uncompressed (it requires more bandwidth)

Do you all have a preference for continuing the conversation here vs in the issue?
I’d like to make sure I understand the advice above:
I tried the steps @lhoestq suggested
```auto
repo_url = 'https://huggingface.co/datasets/dansbecker/hackernews_hiring_posts'
repo = Repository(local_dir=".", clone_from=repo_url)
all_datasets.push_to_hub(repo)
```
That gives an error `AttributeError: 'Repository' object has no attribute 'split'`
I assume the split attribute is specified in the loading script that @lewtun mentioned? I see a `_split_generators` method in that example loading script. Does that create the `split` attribute in some way I’m missing?

Hi,
the `repo` argument should be of type `str`, so try this instead: `all_datasets.push_to_hub("hackernews_hiring_posts")`

Thanks @mariosasko. That works great.
