'sklearn.metrics._pairwise_distances_reduction‘：没有名为ModuleNotFoundError的模块

Question

这是我从sklearn包导入度量时所遇到的错误

Traceback (most recent call last):

我试过了

• 卸载和重新安装scikit学习相关的软件包，如scipy，numpy.
• ，也在度量文件夹中我发现文件
• - Copy.pyd‘...is存在错误原因当我安装sklearn时，我得到了以下warning...is --这是相关的？

DEPRECATION: sklearn is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

我实际上不知道确切原因，但我的问题只是通过更新python(这可能与此无关)和更改我在程序中导入模块的顺序(即pd、np...then sklearn度量模块)来解决的。
