@dmonad do you think this can get in?

Kind ping @dmonad.

Hi @achapkowski, do you mean jupyter_client v6/v7, or [ipywidgets](https://github.com/jupyter-widgets/ipywidget)? It looks more like an ipywidgets issue to me.

I'm wondering how this is related to https://github.com/jupyter/kernel_gateway. Maybe Binder could provide the ability to launch headless remote kernels, instead of having jupyter_client support kernel management through websockets?

I guess we would need to deserialize/reserialize from/to ZMQ sockets to/from websockets, as it's done in Jupyter Server: https://github.com/jupyter-server/jupyter_server/blob/master/jupyter_server/base/zmqhandlers.py And yes I think it would be helpful.

Actually, the need to have a bridge between ZMQ sockets and websockets is only due to the fact that we pass through a server to access the kernel, but it...

Thanks, I think it is https://github.com/Quansight/jhub-client.

I have started https://github.com/davidbrochart/jpterm, that will allow to execute some code or a notebook through a Jupyter server.

Thanks @kloczek for opening an issue. It's strange because the `FileNotFound` exception [should be captured by pytest](https://github.com/jupyter/jupyter_client/blob/4428715b65741ddccac9305d318d4ace08fa711a/jupyter_client/tests/test_multikernelmanager.py#L589-L590). We don't have this traceback in [our CI](https://github.com/jupyter/jupyter_client/runs/5735090927?check_suite_focus=true). Sorry I don't have a...
