How can I update Python in MATLAB?

Answer 1

Documentation states that:

...You cannot switch between versions of Python in a single MATLAB session... If you want to change versions, restart MATLAB and then run pyenv with the new version information.

Set Python Version on Windows Platform
On Windows® platforms, use either:

pyenv('Version','version')

or

pyenv('Version','executable')

ℹ Note: If you downloaded a Python interpreter, but did not register it in the Windows registry, use:

pyenv('Version','executable')

Set Python Version on Mac and Linux Platforms
To set the version, type:

pyenv('Version','executable')

where executable is the full path to the Python executable file.
