lerobot/pusht · Error when downloading dataset with the `datasets`

I'm not sure if this is a problem with the datasets library or this dataset, but when I try to download it with datasets version 2.19.1 I get the following error message:

Try importing lerobot.common.datasets.video_utils. There's some code in there for a registration mechanism that I believe is required for the dataset import to work.

with warnings.catch_warnings():
    warnings.filterwarnings(
        "ignore",
        "'register_feature' is experimental and might be subject to breaking changes in the future.",
        category=UserWarning,
    )
    # to make VideoFrame available in HuggingFace `datasets`
    register_feature(VideoFrame, "VideoFrame")

Edit: And thanks for taking the time to report it!

Thanks @alexandersoare , adding import lerobot.common.datasets.video_utils solved my issue.
I think it would be helpful for others if this instruction was included in the "Use in Datasets library" window.
