每当我尝试在Jupyter notebook上运行以下代码行-从imblearn.under_sampling导入NearMiss进行欠采样(或过采样)不平衡数据时，我得到这个错误：
“”“

对于imblearn.under_sampling，您是否尝试过重新安装该软件包？：
pip install imbalanced-learnconda：
conda install -c conda-forge imbalanced-learn在jupyter笔记本中：
import sys
!{sys.executable} -m pip install <package_name>如果你有scikitlearn>=0.24 (据我所知，现在有一个对imblearn的依赖，就像scikit-learn (>=0.23) https://imbalanced-learn.org/stable/install.html)，你可能想试试：
try:
from sklearn.utils import safe_indexing
except ImportError:
from sklearn.utils import _safe_indexingStack Overflow用户

编辑..\Anaconda3\Lib\site-packages\sklearn\utils\ init.py
复制定义_safe_indexing ...直到下一次定义。并将重命名的代码粘贴到def safe_indexing..
保持以前的_safe_indexing不变。
它解决了这个问题。
