Unable to upload "community provided" dataset - 400 Client Error
Hi ! We're in the process of switching the community datasets to git repos, exactly like what we're doing for models.
You can find an example here:
https://huggingface.co/datasets/lhoestq/custom_squad/tree/main

We'll update the CLI in the coming days and do a new release :)

Also cc @julien-c maybe we can make improve the error message ?
Hi,
i'm trying to a upload a dataset as described [here](https://huggingface.co/docs/datasets/v1.2.0/share_dataset.html#sharing-a-community-provided-dataset). This is what happens:

``` 
$ datasets-cli login
$ datasets-cli upload_dataset my_dataset
About to upload file /path/to/my_dataset/dataset_infos.json to S3 under filename my_dataset/dataset_infos.json and namespace username
About to upload file /path/to/my_dataset/my_dataset.py to S3 under filename my_dataset/my_dataset.py and namespace username
Proceed? [Y/n] Y
Uploading... This might take a while if files are large
400 Client Error: Bad Request for url: https://huggingface.co/api/datasets/presign
huggingface.co migrated to a new model hosting system.
You need to upgrade to transformers v3.5+ to upload new models.
More info at https://discuss.hugginface.co or https://twitter.com/julien_c. Thank you! 
```
I'm using the latest releases of datasets and transformers.
