geometric_mean_score怎么导入python

geometric_mean_score不是Python内置的函数或模块，需要安装第三方库scikit-learn才能使用。可以通过以下命令安装scikit-learn：

pip install -U scikit-learn

然后在Python代码中导入geometric_mean_score函数，示例如下：

from sklearn.metrics import make_scorer
from sklearn.metrics import geometric_mean_score

scorer = make_scorer(geometric_mean_score)

其中make_scorer用于将geometric_mean_score函数转换为scikit-learn中的评分函数。
