Frost number model notebook does not show the air frost numbers?

[iovereem]

I am running the Frost number model Jupyter notebook.
https://pymt.readthedocs.io/en/latest/demos/frost_number.html
Did the installation, then i go to the notebook locally.

I do get a kernel warning and click on 'proceed with this kernel'

Running the steps sequentially in Part 1.
The last step that is supposed to calculate the air frost number for the given input, does not print the output?

Similarly if I try to do it again for the new input conditions, it does not print the output of the calculation.
