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?

I would see if you can open a jupyter notebook and start a notebook with
the mat lab kernel. If not, it either isn’t installed, or maybe is
installed in a different jupyter.

If you get errors here, the issue is outside of org mode. For example, the
hylang kernel quit working for me a while ago.

See
https://github.com/Calysto/matlab_kernel#kernel-times-out-while-starting
for some troubleshooting tips.

It turned out that I need to install
pip3 install --user numpy
pip3 install --user pymatbridge

Where pip3 is the MaCOS 10.15 version

Now everything is fine.

Thanks
