无法从“sklearn.utils.fixes”导入名称“延迟”

Question

How should the cannot import name 'delayed' from 'sklearn.utils.fixes be solved? I have already updated sklearn and upgraded conda as well.

~\.conda\envs\base2\lib\site-packages\sklearn\metrics\pairwise.py in <module>
         30 from ..utils._mask import _get_mask
         31 from ..utils.validation import _deprecate_positional_args
    ---> 32 from ..utils.fixes import delayed
         33 from ..utils.fixes import sp_version, parse_version
         34 
    
    ImportError: cannot import name 'delayed' from 'sklearn.utils.fixes'`

Answer 1

After the installation via pip install delayed and then restarting the kernel, the problem was solved.

Answer 2

Use the following commands:

conda install -c conda-forge imbalanced-learn
conda install nb_conda # to grant to select conda environments as core of jupyter notebook

Answer 3

Restarting the kernel solved the issue for me.
