尽管在 cmd 中使用 pip3 install，导入 sklearn 仍失败

Question

已尝试按顺序执行以下步骤：

1. cmd 提示：

pip3 安装 sklearn

节目

要求已经满足。 sklearn 和 scikit-learn 目录被打印出来

2. Spyder 代码编辑器：

将 sklearn 导入为 sk_learn。 结果：ModuleNotFoundError：没有名为“sklearn”的模块

Windows 10. 更多详情如下：

Answer 1

sklearn是scikit-learn的快捷方式。 你应该试试：

pip install scikit-learn  

根据您的工作环境选择 pip/pip3

还有关于您的 pip 版本的警告，我建议您通过以下方式更新您的 pip

pip install --upgrade pip
