@baraline pls have a look.
and also can you guide me on testing file for this.
thank you.

At first glance the file looks good. I think you can remove the univariate dataset name list, as you pull all the dataset names already.

Concerning the tests, you can look at existing tests file from other loaders, for exemple https://github.com/aeon-toolkit/aeon/blob/main/aeon/datasets/tests/test_data_loaders.py
More specifically, the xxxx_from_repo tests. You can perform a similar test with similar function tags but trying to fecth from Monster, and validate that what you fetched is in the expected format and not empty.

Also, you have some pre-commit failure, you can refer to the developer documentation it explains how to install it, it will correct most of the issues by itself when you try to commit and signal you the others.

@baraline how do i resolve FAILED aeon/datasets/tests/test_monster_loader.py::test_load_monster_dataset - ModuleNotFoundError: No module named 'huggingface_hub'.
i tried removing _check_soft_dependencies but still same error.

[baraline]

The check soft dep should stay, it is used to check if the dependency is installed (as it is optional) and raide appropriate messages to the users. Don't have access to my computer rn, so add the check soft dep back and i'll check the errors throwed when I can later

[baraline]

Test are failing because the test skip is wrongly parameterized. The wrong check is applied to validate if the test should be run or not. You should do

    @pytest.mark.skipif(
        not _check_soft_dependencies("hugging-face", severity="none"),
        reason="required soft dependency hugging-face not available",
    )

Instead of

@pytest.mark.skipif(
    PR_TESTING,
    reason="Only run on overnights because of read from internet.",
)

[baraline]

You should test with huggingface-hub (the dependency you added in the project.toml), not with hugging-face. You correctly did it when you created the loader like this :

_check_soft_dependencies("huggingface-hub", severity="none")
from huggingface_hub import hf_hub_download

My example didn't take the correct name.

my bad!!
did it in a hurry

[baraline]

The remaining failure is not linked to what you did, so we should be good to go. We'll just wait for it to be resolved. Thanks !
