ImportError: cannot import name 'DataFrameTreeReduction' from 'dask.layers' (/home/kratsg/athena-dev/venv/lib/python3.11/site-packages/dask/layers.py)

This is because DataFrameTreeReduction got removed in dask/dask#11606 . So to be compatible, one needs

python -m pip install 'dask[array,distributed]<2025'

will be resolved by dask-contrib/dask-awkward#566
