Error: 'unable to contact kernel' on Jupyter 3.2.x +

[brylie]

When running these notebooks on Jupyter 3.2.x or 4.2.x, I get the following error:

Failed to start the kernel

The 'None' kernel is not available. Please pick another suitable kernel instead, or install that kernel.

Note, the Kernel is running when I create a new notebook, so the problem seems to be related to incompatibility between these notebooks and Jupyter.

Environment

localhost

Here is my local Environment:

The version of the notebook server is 4.2.1 and is running on:

[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)]

Current Kernel Information:

The version of the notebook server is 3.2.0-8b0eef4 and is running on:

I'm updating the notebooks later this week and will let you know what I find out. Thanks!

@brylie I just updated the notebooks today. Hopefully that resolves the issue, but please let me know if the issue persists!
