Hello:
I've been trying to set up a Jupyter environment with the Guix kernel inside a
guix environment using:
`guix environment --ad-hoc guix-jupyter jupyter -- jupyter notebook`.
Jupyter starts up fine, but when I create an empty notebook with the Guix kernel
it spams Nudge messages in the console, followed by a crash:
```
[W 16:25:40.117 NotebookApp] Nudge: attempt 120 on kernel

```
Attempting to run anything in the notebook such as
`;;guix environment matplotlib-env <- python-ipykernel python-numpy
python-matplotlib`
simply does nothing. I'm not sure if this is an issue with me misconfiguring
something or if it's actually a bug, but I haven't been able to chase it down
as I don't really understand the internals of Jupyter all that well.
Adding `python-ipykernel` and using a Python kernel works fine.
