Failed to start the Kernel

Hello Team,

Whenever I am opening my Jupyter Notebook in Dataiku DSS, I am getting Kernel Error. 

Below is the error message:

Can someone help me to resolve this issue at the earliest.

 

My Dataiku is running on Unix AWS VM.

Hi @SAJIN ,

Do you have UIF enabled on your instance? This error is a little generic and we will need an instance diagnostic to review the logs and diagnose the issue.

You can submit a support ticket to https://support.dataiku.com/support/home
where we can better assist you.
