We are planning to support the conversion to LeRobot Dataset v3.0 format in the future, but for now, we only support the conversion to LeRobot Dataset v2.1 format.
If you want to convert to the LeRobot Dataset v3.0 format please check the article below:
[LeRobot Dataset v3.0 format conversion](https://huggingface.co/docs/lerobot/porting_datasets_v3#migrating-from-dataset-v21)
Also, you can convert to the LeRobot dataset v3.0 format by changing the `--format` argument to `lerobot_v3.0`. The v3.0 format is the latest version of the LeRobot dataset format, which has some changes in the file structure and metadata format. Please refer to the [LeRobot dataset documentation](https://huggingface.co/docs/lerobot/lerobot-dataset-v3) for more details on the dataset format.
