清除pip的scikit-learn cache安装包

要清除pip的scikit-learn cache并重新安装包，可以使用以下步骤：

1. 使用以下命令清除pip的cache：

pip cache purge

2. 然后使用以下命令重新安装scikit-learn包：

pip install -U scikit-learn

这个命令会更新scikit-learn包到最新版本，并且会下载并安装最新的软件包，而不是使用缓存的软件包。如果你想安装特定版本的scikit-learn包，可以使用以下命令：

pip install scikit-learn==<version>

将`<version>`替换为你想要安装的版本号。

这个错误报告表明在安装 scikit-learn 时发生了一个网络连接错误，可能是由于连接超时或网络不稳定等问题导致的。你可以尝试重新运行 `pip install scikit-learn` 命令，或者检查网络连接是否正常。如果问题仍然存在，你可以尝试使用其他镜像源进行安装，或者手动下载 scikit-learn 的安装包进行安装。
