你可以直接在打开的笔记本上完成:

!pip install jupyterthemes
!jt -t chesterish

重新启动主题应用程序的jupyter服务器

而不是在Jupyter内部安装一个库，我建议你使用Chrome中的“黑暗阅读器”扩展(你可以在其他浏览器中找到“黑暗阅读器”扩展，例如Firefox)。 你可以玩它;过滤URL(s)你想有黑暗主题，甚至如何定义黑暗主题为自己。 下面是几个例子:

我希望这能有所帮助。

conda install jupyterthemes

在Windows系统中不适合我。我用的是水蟒。

但是,

pip install jupyterthemes

在Anaconda Prompt工作过。

另一个选择是如果你使用谷歌chrome，想要一个黑暗的主题，让你在jupyter/网页上工作几个小时更容易，同时也让你的代码中的配色方案可读，那就是在实验中使用“Web内容的自动暗模式”标志- chrome://flags -我通常会选择“启用选择性图像反转”选项。

如果在尝试使用PIP时出现错误，您可以使用CMD并运行您的命令。

暗模式:-

我已经使用Raleway字体样式

到C:\User\UserName\.jupyter\custom\custom.css文件

附加给定的样式，这是专门为黑暗模式的jupyter笔记本…

这应该是您当前的custom.css文件:-

/* This file contains any manual css for this page that needs to override the global styles.
    This is only required when different pages style the same element differently. This is just
    a hack to deal with our current css styles and no new styling should be added in this file.*/
