Hi, I am trying to integrate jupyterhub with enterprise_gateway. EG+nb2kg+Notebook have already worked well. I configured jupyter_notebook_config.py as another issue indicated:
`from nb2kg import managers
c = get_config()

c.NotebookApp.session_manager_class=managers.SessionManager
c.NotebookApp.kernel_manager_class=managers.RemoteKernelManager
c.NotebookApp.kernel_spec_manager_class=managers.RemoteKernelSpecManager`

However, the jupyterhub cannot find the kernels and the error is：

[E 2019-03-27 16:47:34.599 SingleUserNotebookApp web:1788] Uncaught exception GET /user/tank/api/kernelspecs (127.0.0.1)

I was wondering what else should I configure or maybe I need to get another version of nb2kg?
I went over #448 but am still confused. Thank you!

you need to import nb2kg in notebook config as below:
import nb2kg
from nb2kg import managers

Please try this. Thanks.

Can you share your notebook and hub config? That’ll help me .

Ensure you have the extension configured (via jupyter serverextension enable --py nb2kg --sys-prefix) and I'd drop your from nb2kg import managers and prefix your class changes with nb2kg. so that it matches these.

FYI, here is what I use for JupyterHub integration:

JupyterHub Configuration

Jupyter Enterprise gateway ingress to make it available at /gateway

BTW, I mostly tried using in Kubernetes, not sure if using a different environment requires specific tweaks but this can give you a bases. Also, all steps are documented in the ansible-scripts we use for setting up test environments.

Thank you, and I am trying to make jupyterhub work on yarn cluster according to your configuration. I will update.

this is because the manager class does not get nb2kg class, it is a configuration issue, the default manager class does not have method of list_kernel_specs and this method is written in nb2kg

see this nb2kg issue to fix

Thanks for the update @Litchilitchy. @jrcblue - how are things going for you? Have you been able to move forward?

@jrcblue - thank you for the response - glad you're moving forward. I'm closing this issue.

Could you please open a separate issue regarding the inability to unset unauthorized_users? Thank you.
