When running jupyter, it seems that the python in "/usr/bin/python"
instead of the one in store is used. Here is the complete logging of
jupyter console output, notice those line in the middle, where displaying:
"/usr/bin/python: No module named ipykernel_launcher"

I wonder if that’s by design. As far as I understand Jupyter can be
used with many different kernels, including different versions of
Python. This means that we may not limit it to just a single version of
Python at build time.
Is this correct?
I do agree, though, that the default doesn’t seem right. As long as a
user can override the kernel to use a different Python than the one we
configured at build time, I think we should default to the current
version of Python in Guix.

Actually the only command I know about jupyter is how to open a
notebook :) . But it asks me to restart the kernel again and again in
browser. And according to the console, it seems that jupyter couldn't
find the needed kernel because the kernel is installed in guix store,
not in normal system path, but jupyter itself is ran by system
python other than the one installed in guix store.
And, maybe I am wrong, packages that installed by guix should never use
software not in the store, right?

Yes. Installed kernels are normally under $prefix/share/jupyter/kernels.
A standard installation of Jupyter via PyPI also installs a kernel for
the same Python interpreter that is used for Jupyter. Additional kernels
can then be installed afterwards.

You could run
jupyter kernelspec list
to see which kernels Jupyter actually uses.

So my understanding is that there’s no bug on our side, right?
Thanks,

That depends on what you call a bug.
The current behavior of the Guix package for Jupyter is not in conflict
with any written documentation for Jupyter, but does not respect a
convention that standard installations (via pip, for example) do
respect. This convention says that the default Python kernel for Jupyter
uses the same Python installation as Jupyter itself.
I'd vote for respecting this convention, and I'd be happy to work on an
implementation, but don't count on me for this before August.
Konrad.

Oh, got it.

Alright, we’ll see!
