无法从“sklearn.utils.fixes”导入名称“延迟”

应该如何cannot import name 'delayed' from 'sklearn.utils.fixes解决？我已经更新了 sklearn 并升级了 conda。

~.condaenvsbase2libsite-packagessklearnmetricspairwise.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'`
