如何从私有Pypi存储库将python包安装到google Colab？

我的公司已经开发了python包，并将它们托管在一个私有的Pypi存储库中。我希望在Google Colab笔记本上安装这些软件包

如果它们位于公共Pypi存储库中，则可以：

!pip3 install --index-url=https://pypi.spotify.net/spotify/production confidence

但是，它会导致以下错误：

我怀疑这是因为GoogleColab是一个托管笔记本。这意味着它不是通过我的工作wifi连接到Pypi，而是通过谷歌服务器连接到Pypi。

您需要：

• 使包存储库可用于公共internet（不太可能您真的想要这样做）
• 将Colaboratory连接到本地运行时：

这感觉很有意义：回购是否有可能是在代理背后？如果是这样，您如何在托管笔记本的系统中设置代理设置？
