我正在尝试导入from sklearn.metrics.pairwise import pairwise_distances 但显示以下内容：

ImportError: cannot import name extend_notes_in_docstring

from sklearn.metrics.pairwise import pairwise_distances
Traceback (most recent call last):

ImportError: cannot import name extend_notes_in_docstring

在导入pairwise.distances之前还有其他依赖库要导入吗？
