我正在尝试导入 dask_searchcv 并在导入其他模块时引发错误DeprecationDict。

我已经安装了 dask_searchcv 版本：0.2.0 和 scikit-learn 版本：0.21.3

我尝试导入 dark_searchcv，如下所示：

import dask_searchcv as dcv

我收到以下错误消息：

ImportError                               Traceback (most recent call last)

     55     _RETURN_TRAIN_SCORE_DEFAULT = 'warn'
     56 

ImportError: cannot import name 'DeprecationDict'

我尝试使用重新安装 sklearn，pip3 install -U scikit-learn但问题仍未解决。

注意：我正在使用 jupyter notebook 运行上面的代码

dask-searchcv已弃用，如文档中所述：https ://dask-searchcv.readthedocs.io/en/latest/

您想要dask-ml并且应该将导入更新为import dask_ml.model_selection as dcv.
