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

Can you paste the code you executed that resulted in this console log? A minimal reproduction if possible.

The mention of nosniff may be a clue - it could be your local browser/firewall configuration (similar to this issue: https://stackoverflow.com/a/53062522)

This is working fine with jupyter lab, only issue is with jupyter notebook.
However I turned to jupyterlab while working with Altair charts.

I just noticed jupyter-vega.js is not loading in the browser, infact I saved 'jupyter-vega.js' on my desktop and found no script was in the file i.e, it was a blank file.

import altair as alt
from vega_datasets import data
alt.renderers.enable('notebook')

source = data.seattle_weather()

alt.Chart(source).mark_bar(
    cornerRadiusTopLeft=3,
    cornerRadiusTopRight=3
).encode(
    x='month(date):O',
    y='count():Q',
    color='weather:N'
)

Thanks. My current guess is it's a browser configuration/firewall issue as I mentioned above. I'm not sure I'm going to be able to help beyond giving you that bread-crumb trail to follow.

I suggest you look into your local browser/firewall configuration to try and figure out why it's blocking the page from loading the javascript associated with the ipyvega nbextension. Unfortunately, that's not something that's easy to help with from afar.

Thank you for your great help and suggestion. I will look into your comments and figure it out if possible with me. Meantime I have jupyter lab, and will progress with it.

I have the same issue using vega example notebook, except no error is displayed in the web developer console.

Altair in the same notebook renders perfectly.
