title: jupyter python notebook showing kernel error
body: <p>I am accessing jupyterhub notebook through browser as it is running on a remote server(using nginx so that jupyterhub is accessible to client machines).When I access the notebook a kernel error is shown at the top of the screen. Jupyterhub and jupyter notebook is running on a kubernetes cluster and the jupyter notebook is a custom built docker image suitable for python programming. I am very new into python/jupyter hub/notebook, please suggest how to resolve the kernel error.<a href="https://i.stack.imgur.com/T3HCj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/T3HCj.png" alt="enter image description here"></a></p>
