AttributeError: module 'skdatasets.repositories' has no attribute 'cran'" }

Hello, I encountered an issue while running an example from the scikit-fda documentation. Specifically, when I try to load the phoneme dataset fetch_phoneme, I get an AttributeError.
`import skfda

Trying to load the phoneme dataset

X, y = skfda.datasets.fetch_phoneme(return_X_y=True)`

AttributeError Traceback (most recent call last)

AttributeError: module 'skdatasets.repositories' has no attribute 'cran'

I installed the library using pip install scikit-fda.
I suspect there might be an issue with the skdatasets dependency.
I am unsure if there is a workaround or if my installation is missing something.

Is this a known issue with skfda or its dependencies?
Should I downgrade my Python version or a specific package to avoid this error?
Are there any alternative ways to access the fetch_phoneme dataset?
Thank you in advance for your help!

Could you please post your version of scikit-fda and scikit-datasets?

[yn-zpc]

The scikit-fda version is 0.9.1. The scikit-datasets version is 0.2.4

[vnmabus]

Maybe it is better to know also the version of the numpy, pandas, scikit-learn and rdata packages. When installing scikit-fda it should have installed scikit-datasets[cran], which in turn should have installed these.

The module cran is only present if there is no error importing some functionally from these packages, so it can either happen that some of these got removed/downgraded or that a new version removed some functionality.

Ok, no, disregard the above. It seems that the culprit is indeed distutils, which is no longer available in Python 3.12. We need to patch scikit-datasets to remove this dependency.
