V30_MESSAGE = """
|
|
The dataset you requested ({repo_id}) is in {version} format.
|
|
|
|
We introduced a new format since v3.0 which is not backward compatible with v2.1.
|
|
Please, update your dataset to the new format using this command:
|
|
```
|
|
python -m lerobot.datasets.v30.convert_dataset_v21_to_v30 --repo-id={repo_id}
|
|
```
|
|
|
|
If you already have a converted version uploaded to the hub, then this error might be because of
|
|
an older version in your local cache. Consider deleting the cached version and retrying.
|
|
|
|
If you encounter a problem, contact LeRobot maintainers on [Discord](https://discord.com/invite/s3KuuzsPFb)

or open an [issue on GitHub](https://github.com/huggingface/lerobot/issues/new/choose).

FUTURE_MESSAGE = """
