What happened: I installed dask ml by pip3 install git+https://github.com/dask/dask-ml.git But when tried importing dask ml got this error -

Anything else we need to know?: My scikit-learn version is 1.0.1. I tried downgrading to 0.21 but still getting same issue.

• Dask version: 2.30.0
• Python version: 3.8.10
• Operating System: Ubuntu 20.04
• Install method (conda, pip, source): pip

Sounds like a bad scikit-learn install. Can you try creating a new environment?
