> I think in jupyter this is meant to be handled by the --kernel option - ie
> jupyter qtconsole --kernel python2
ok it works
> jupyter qtconsole --kernel python3
$ jupyter qtconsole --kernel python3

jupyter_client.kernelspec.NoSuchKernel: No such kernel named python3
given the existence of non-python kernels (irkernel, ihaskell, iruby,
ijavascript, etc...)
But if I list the kernel available I have just
~$ jupyter-kernelspec list
Available kernels:
python3 /usr/lib/python3/dist-packages/ipykernel/resources
so it is really strange...
Cheers
