The kernel might require python3.

Thanks for pinting it out to me. Couldn't install it so far
ImportError: No module named pathlib
when trying directly to use >python -m matlab_kernel install

Or ould not find a version that satisfies the requirement backports.tempfile (from matlab-kernel) (from versions: 1.0rc1, 1.0rc1)
Cleaning up...
No distributions matching the version for backports.tempfile (from matlab-kernel)
Storing debug log for failure in /home/oub/.pip/pip.log

Have to write the author.

The output using your code and Eric's suggestion is ok but I am curious
to see what the kernel is supposed to do better.
