Question

I\'m having troubles installing extensions in IPython. The problem is that i can\'t get the extensions load automatically, i have followed the instructions in the github pag

There's been a little change to the syntax. Nowadays, $ might not be defined by the time your custom.js loads, so instead of something like

$([IPython.events]).on("app_initialized.NotebookApp", function () {
    IPython.load_extensions("whatever");
});

you should do something like

require(['base/js/namespace', 'base/js/events'], function(IPython, events) {
    events.on('app_initialized.NotebookApp', function(){
        IPython.load_extensions("whatever");
    })
});

with the appropriate changes to braces and parentheses. For me, the former will work more often than not, but certainly not always; it fails maybe ~1/3 of the time.

If that doesn't do it for you, open up Developer Tools (or whatever is relevant for your browser) and look at the javascript console for errors. That'll help figure out what's going wrong.
