Also, are you able to verify that the 'python2' or 'python3' that you
get when you run it from a terminal is the same as the one that Octave
tries to run?

Can you try something like 'which python3' in a terminal, and compare it
with 'system "which python3"' in Octave?

As I understand it, you might easily have versions of Python installed
with Homebrew and with pyenv, for example, and the one that Octave finds
is not the same as the one you use in a terminal.
