With my Datalab instance, I can't run my script because the Kernel is dead and i don't have any option to select Python3 or Python 2.
I restarted the session and tried also to restart the VM also, but nothing changed, the Kernel option is still unavalaible to choose!
Can you help please?
There's an issue when connecting to Datalab from the Cloud Shell. You can workaround this issue by connecting to the instance without Cloud Shell and create a tunnel on port 8080 to display the Datalab UI on your machine.
In addition, I suggest switching to AI Platform Notebooks which provides an easy to use managed JupyterLab VM similar to Datalab and don't have this issue. Here's the quickstart to create a notebook.
