Pyodide Kernel: Unknown Status

[sean-morris]

@jtpio @balajialg @ericvd-ucb
Once JupyterLite renders itself, sometimes the Pyodide Kernel does not "connect".

You can see the message when you mouse over the Pyodide Kernel indicator in the top-right corner of the notebook.

In this case, the indicator says: "Kernel Status: Idle"

Sometimes, it says: "Kernel Status: Unknown".

If you run a cell, it will never complete.

We have worked around this problem, by:

1. Closing the tab and re-opening it; or
2. By selecting "Restart Kernel..." from the Kernel menu.
   

It seems to happen fairly regularly. Is there something we are doing wrong with the deployment? Is there a better way to resolve the problem when it does occur?

Thanks.

Normally the kernel should indeed indicate "Kernel Status: Unknown" first while initializing.

And the "Kernel Status: Idle" which is normal.

I played with different notebooks on http://www.data8.org/materials-sp22-jupyterlite/ but didn't notice this. Which browser are you using?

It is Chrome. I am going to keep eye on this to see if I can find some sort of pattern related to this kernel issue.

Thanks again.
