To determine if your system has a supported version, use the
The value set by
pyenv is persistent across MATLAB sessions. If you have multiple supported versions, use
pyenv to display the default version used by MATLAB.
You cannot switch between versions of Python in a single MATLAB session. MATLAB automatically selects and loads a Python version when you type a Python command, such as:
If you want to change versions, restart MATLAB and then run
pyenv with the new version
On Windows® platforms, use either:
If you downloaded a Python interpreter, but did not register it in the Windows registry, use:
To set the version, type:

The architecture of Python must match the architecture of MATLAB. For more information, see Install Supported Python Implementation.
On Linux® and Mac systems, if you build the Python executable,
configure the build with the
