Issue with dask_ml

[mad-stat]

I am facing this issue every time I tend to use dask for my ML project. Even I tried to follow the XGBoost.ipynb file of the dask-examples repository but this error crops up whenever I am trying to import stuffs from dask_ml

cannot import name '_is_constant_feature' from 'sklearn.preprocessing._data' (/opt/conda/lib/python3.7/site-packages/sklearn/preprocessing/_data.py)
