python - 导入 Sklearn 时出现错误

问题描述

尝试导入时出现错误import sklearn.metrics.pairwise as pw如何解决？

完全错误：ImportError: DLL load failed while importing _arpack: 找不到指定的过程。

导入：将 sklearn.metrics.pairwise 导入为 pw

解决方案

尝试删除并重新安装 sklearn 包

conda remove --force numpy, scipy, scikit-learn

或者

conda remove scikit-learn

并安装使用pip

pip install -U scikit-learn
