some progress matlab-kernel, a python path problem?

[Uwe Brauer <oub@mat.ucm.es>]

Hi

So I switched from finks python 3.7 to MacOS 3.8
I think I set all paths (mac does not locate them in 
HOME/.local but in 
HOME/Library

However when I fire up the org-babel command the iphthon console reads
as

But the matlab_kernel is installed

I am puzzled, any python guru could enlighten me please?
