Jupyter notebook is not displaying charts inline.

[dove88]

Hello, I am trying to render Altair charts in jupyter notebook, but I am getting only blank inline output.
I am using "alt.renderers.enable('notebook')" renderer option in my jupyter notebook.
'Mimetype' renderer is working fine in jupyter lab.

I have attached browser console for more details, kindly advise me to how can I solve the issue?

Altair version - 4.2.0
Vega version - 3.6.0
Jupyter notebook version - 6.4.10
ipykernel 6.4.1
ipython 8.2.0
ipywidgets 7.6.5
Browser Mozilla Firefox

Please do the needful
Thank you

Does it work in the notebook with alt.renderers.enable('default')? If that doesn't work, there are some additional tips on this page in the docs that you can try out https://altair-viz.github.io/user_guide/troubleshooting.html. You could also try in another browser refine what is going wrong.

Hello, I have tried with Google Chrome first, then I shifted to Firefox, to check whether the case of browser issue. In both cases, it doesn't work. Infact I am using latest version of both browsers.
I did change, the renderer option to 'default' before I posted this thread and also gone through the display troubleshot website contents too.
Nothing worked till now.
I was using node 14 version, but yesterday I installed latest stable version for checking the compactibilty issue, however the issue remains the same.

This is for your info please.

I have vscode jupyter notebook and jupyterlab, the Mimetype is working fine in both these applications.

I think vega.js is not loading while executing python code?

Hmmm, the only additional thing I can think of is if you have a browser addon that blocks the connection. I would try in a private/incognito window with all addons disabled. It is possible that this could be why you see blocked due to mimetype mismatch vega, but there might be other reasons. This seems to be more directly related to Vega and JupyterNotebooks so I would try asking in https://github.com/vega/ipyvega for more help

You might be right...
I have gone through the link that you have provided in the reply, and this command,
'pip install jupyter pandas vega'.
Is it a separate installtion than my previous installtion of jupyter notebook, pandas, Vega?
Since I have installed all of these packages, do I need to install again with one line command?

[joelostblom]

This error should not be related to your installation of those packages. I am closing this in favor of vega/ipyvega#412 since I am not sure if there is anything additional to add beyond what is mentioned there regarding the firewall.
