Hi,
chapter 2 of the book uses Voila to turn the bear classifier notebook into an app.
I am running Jupyter via Google Cloud.
Installing Voila works fine, but when registering it with Jupyter I get the below error message.
Did somebody come along this?
Is there a fix?
Or is there a principle issue with using voila via Google Cloud?
thanks a lot
Norbert
