jupyter 4 notebooks not launching

[michaelaye]

Installed via conda today.

The dashboard is launching fine. But neither a new notebook or the Ipython 3.2.1 notebooks are launching, they are stuck with this kind of display status:

I checked the error console and the first thing it does not seem to like is a reference to the gist plugin I had installed in IPython 3 but that does not seem everything. I can not afford to stay on this version as I need the notebook to be working, so I'm afraid I can't do any further debugging than this.

I'm guessing a clean install without heritage from IPython 3 would have less problems so any hint how I can do that would be appreciated. Thanks!

Oh, I also got this in the terminal, but not much saying there, the line with Creating new notebook in is where it's stuck when trying to launching a new notebook.

I also can report that new notebooks had been created in the folder where I launched them, and I can open them with IPy3 notebook.

[Carreau]

Remove temporarly your custom.js from ~/.jupyter/custom. the rest of the errors don't matter.

[Carreau]

Also once you remove your custom.js you might want to post it here so that we can fix it.

[michaelaye]

I put the custom.js here as a gist:
https://gist.github.com/9ecb5830ea89c701d142

[michaelaye]

Errm, I deleted the custom.js completely and it's still being found? Still stuck at opening a new notebook.

[Carreau]

So if you are "just" loading extensions (and if gist.js is sufficiently up to date). the see here (TL;DR) , here (longer explanation) on how to write and load extensions in a way which is not subject to race condition.

Which roughly in your case is removing custom.js and execute only once in the notebook:

IPython.notebook.config.update({
  "load_extensions": {"gist":true}
})

[Carreau]

You need to restart the server. and check custom js both in ~/.jupyter and ~.ipython/profile_default

[Carreau]

Try also a force refresh in case Safari is cahing things.

[michaelaye]

After renaming the custom.js in ~/.ipython/profile_default a new notebook now launched.
I cannot execute the above IPython.notebook.config.update() command because IPython does not have a module called notebook anymore?

[Carreau]

Sorry should have precised , the above command should be in the JS console.

If things are found in ~/.ipython/profile_default that you might have a 1/2 IPython 3.x 1/2 IPython 4.x System.

[michaelaye]

That would be the result of the conda install jupyter then. What do I need to remove to make it only IPy 4.x?

[mpacer]

So I just ran into this problem(see below for exact warning output) on the command line as well though my actual notebooks open just fine.

/usr/local/lib/python3.4/site-packages/IPython/kernel/__init__.py:13: ShimWarning: The IPython.kernel package has been deprecated. You should import from ipykernel or jupyter_client instead. "You should import from ipykernel or jupyter_client instead.", ShimWarning)

My guess is that it relates to my previous customization in the ipython profile stuff and though it did copy it over to .jupyter when I first ran the notebook, now the existence of both sets of files is causing some kind of confusion.

[michaelaye]

i have that as well everywhere I run Jupyter/IPy 4.x? Thought that it was just a transitional feature? So I have a messed up set-up?

[mpacer]

Hmm, so maybe you're right and it is a transitional feature…I just moved my ~/.ipython file to ~/.ipythontest and its not producing any errors beyond the warning that we've already pointed out. So it can't just be that…
