您可以使用运行笔记本中的set_nb_theme更改主题

!pip install jupyterthemes

from jupyterthemes import get_themes
import jupyterthemes as jt
from jupyterthemes.stylefx import set_nb_theme

set_nb_theme('chesterish')

从https://www.kaggle.com/getting-started/97540粘贴

简单，Jupyter字体大小和内外背景颜色的全局更改(此更改将影响所有笔记本电脑)。

在Windows下，通过运行命令找到config目录: jupyter——config-dir

在Linux中是~/.jupyter

在此目录中创建子文件夹custom 创建文件custom.css并粘贴:

/* Change outer background and make the notebook take all available width */
.container {
    width: 99% !important;
    background: #DDC !important;
}   

/* Change inner background (CODE) */
div.input_area {
    background: #F4F4E2 !important;
    font-size: 16px !important;
}

/* Change global font size (CODE) */
.CodeMirror {
    font-size: 16px !important;
}  

/* Prevent the edit cell highlight box from getting clipped;
 * important so that it also works when cell is in edit mode */
div.cell.selected {
    border-left-width: 1px !important;
} 

最后，重启Jupyter。结果:

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.*/

使用FireFox插件“暗黑木星”。

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。
