When using the JupyterLab found within the azure ML compute instance, every now and then, I run into an issue where it will say that network connection is lost.
I have confirmed that the computer is still running. the notebook itself can be edited and saved, so the computer/VM is definitely running Of course, the internet is fully functional
On the top right corner next to the now blank circle it will say "No Kernel!"
We can't repro the issue, can you help gives us more details? One possibility is that the kernel has bugs and hangs (could be due to extensions, widgets installed) or the resources on the machine are exhausted and kernel dies. What VM type are you using? If it's a small VM you may ran out of resources.
