Hello,

rapid-dasks cannot import on python 3.11+

I see you are pinning "dask==2024.1.1" in your pyproject.toml
https://github.com/rapidsai/rapids-dask-dependency/blob/main/pyproject.toml

dask 2024.1.1 cannot load on python 3.11
The issue is fixed in dask 2024.4.1
dask/dask#11035

Could you remove the pinning?

It should be the case that if rapids-dask-dependency is installed in the environment, then it patches dask.dataframe on import such that this works even in py3.11+

(see #41)

Presently, there will also be a 24.06 release which pins to a more recent dask. Can you use that instead?

[morotti]

Thanks, we can use 24.06 when you make a new release.

Thanks, we can use 24.06 when you make a new release.

Sounds good - That should resolve the issue.

Regarding 24.04: How did you install rapids (cudf/dask-cudf)? Do you have rapids-dask-dependency installed?
