推荐答案

基于this问题和找到的选项此处:
在您的 custom.js 文件(位置取决于您的操作系统)中放入

Based on this question and the options found here:
In your custom.js file (location depends on your OS) put

IPython.Cell.options_default.cm_config.indentUnit = 2;

在我的机器上，文件位于 ~/.ipython/profile_default/static/custom

On my machine the file is located in ~/.ipython/profile_default/static/custom

在 IPython 3 中，普通调用不再起作用，因此需要将设置放置在适当的事件处理程序中.一个可能的解决方案可能看起来像

In IPython 3 the plain call does not work any more, thus it is required to place the setting within an appropriate event handler. A possible solution could look like

define([
    'base/js/namespace',
    'base/js/events'
    ],
    function(IPython, events) {
        events.on("app_initialized.NotebookApp",
            function () {
                IPython.Cell.options_default.cm_config.indentUnit = 2;
            }
        );
    }
);
