I'm having the problem that I like my notebooks slimmer than is required to prevent an annoying temporary layout change caused by the display of the automatic checkpoint creation.

In this screenshot:

one can see the empty space between the menu entry "Help" and the "Trusted" status icon.
This space is being used by the "Checkpoint created" notification that temporary pops up, with the interval of the automatic checkpoint creation.

Now, whenever the browser window is sufficiently slim, so that the

Checkpoint created <timestamp>

does not fit into this space, the layout manager temporarily creates a new line in the header, and the whole notebook is scrolling down one line, only to scroll up one line a few seconds later. I find this behavior highly annoying, so I would like Jupyter to do its checkpoints withOUT telling me about it. I really don't require this notification.
Is that possible to configure somehow?

It looks like disabling two event handlers should achieve result you need. Just put code below in the first cell of your notebook

%%javascript

IPython.notebook.events.off('checkpoint_created.Notebook');

IPython.notebook.events.off('notebook_saved.Notebook');

I've found these handlers in code of jupyter notebook:

• checkpoint_created.Notebook


• notebook_saved.Notebook

Creating a nbextension

If you require the behavior on all your notebook i suggest creating a simple nbextension.

First, create the extension directory under directory path you want:

$ mkdir -p ~/Documents/checkpoint_disable

Create main.js file in above dir

Contents of main.js:

define([

    'require',

    'jquery',

    'base/js/namespace',

], function (

    requirejs,

    $,

    Jupyter,

) {

    "use strict";



    var initialize = function () {

        Jupyter.notebook.events.off('checkpoint_created.Notebook');

        Jupyter.notebook.events.off('notebook_saved.Notebook');

        Jupyter.notebook.events.on(

            'notebook_saved.Notebook',

            function() {

                console.log('Notebook saved');

            })

    };



    var load_ipython_extension = function () {

        return Jupyter.notebook.config.loaded.then(initialize);

    };



    // return object to export public methods

    return {

        load_ipython_extension : load_ipython_extension

    };

});

NOTE Disabling two mentioned event handlers affects only UI. Under the hood notebook is still being autosaved if there is new content since last save

Installing nbextension

You need to use jupyter-nbextension command provided already with jupyter.

First install the extension

$ jupyter-nbextension install --user ~/Documents/checkpoint_disable

Next enable the extension

$ jupyter-nbextension enable checkpoint_disable/main

You can check that extension is installed by invoiking

$ jupyter-nbextension list

And you're done. The extension should load automatically.
You can verify that it is true if you see in browser javascript console log similar to one below:

load_extensions 

Arguments { 0: "jupyter-js-widgets/extension", 1: "checkpoint_disable/main", … }

utils.js:60

Loading extension: checkpoint_disable/main
