使用conda直接安装Jupyterthemes包，使用:

conda install -c conda-forge jupyterthemes

然后，正如其他人指出的那样，使用jt -t <theme-name>更改主题

如果有人有兴趣在启用主题的docker中运行anaconda

docker run -t --rm -p 8888:8888 -v $(pwd):/opt/notebooks continuumio/anaconda3 /bin/bash -c "pip install jupyterthemes; jt -t onedork; /opt/conda/bin/jupyter notebook --ip=0.0.0.0 --port=8888 --notebook-dir=/opt/notebooks --allow-root --no-browser;"

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.*/

遵循以下步骤

使用pip安装jupyterthemes:

pip install jupyterthemes

然后从下面选择主题，并使用以下命令设置它们。一旦成功安装，我们中的许多人认为我们需要再次启动jupyter服务器，只需刷新页面。

使用以下命令设置主题:

jt -t <theme-name>

可用的主题:

onedork grade3 oceans16 chesterish monokai solarizedl solarizedd

可用主题的截图在其Github存储库中。

在设置主题时，还可以在同一个命令中指定-T(——toolbar)来保留工具栏，否则工具栏将不显示。如需帮助，请输入jt -h。

在我改变主题后，它表现得很奇怪。字体很小，看不到工具栏，我真的不喜欢这个新外观。

对于想要还原原有主题的用户，可以按照以下步骤进行操作:

jt -r

您需要在第一次这样做时重新启动Jupyter，之后刷新就足以启用新主题。

或者直接从笔记本里

!jt -r

使用Kyle Dunovan的jupyter-themes包很容易做到这一点。您可以使用conda安装它。否则，您将需要使用pip。

使用conda安装:

conda install -c conda-forge jupyterthemes

或小毛病:

pip install jupyterthemes

你可以通过以下方法获得可用主题的列表:

jt -l

所以改变你的主题:

jt -t theme-name

要加载主题，最后，重新加载页面。文档和源代码都在这里。在设置主题时，还可以在同一个命令中指定-T(——toolbar)来保留工具栏，否则工具栏将不会显示。如需帮助，请输入jt -h。
