Description

Hi there !
I have a problem. I've installed Jupyter on my VPS. All work fine except the notebook ( and this is a big thing ). I type "import math" for example and run it; i got this. I paste here my console
`
[I 12:57:52.183 NotebookApp] Creating new notebook in

So it doesn't work ...
Thanks !

Research direction

No source file or test is named. Start by reproducing the kernel_info timeout from the NotebookApp log on a comparable VPS, then inspect the Python 3 kernel startup and connection path. Done means the notebook receives kernel_info and executes "import math" without timing out.
