如何在 Jupyter 单元上运行 PIP 安装命令

Question

我认为我们可以通过在 Jupyter 单元上运行类似的操作来运行 PIP 安装或 PIP 卸载。

%pip 安装 myPackage

但系统会提示我这样确认：

继续（是/否）？

如何克服这个问题并在单元中运行 PIP？

Answer 1

您是否尝试过以这种方式安装而不是使用魔法？

!pip install <package>

一般来说，这不会提示您继续。

顺便说一句，您要安装哪个软件包？我已经尝试过使用!pip和 的两种方法%pip。使用%pip并没有要求我继续，而是要求我重新启动内核。

%pip install folium
