How do I troubleshoot a MATLAB crash when trying to use the Python Interface?

Whenever I try to use some Python functions in MATLAB using the Python Interface, my MATLAB crashes. What can I do to avoid such a crash?

If MATLAB crashes when you try to use the Python Interface for MATLAB, then this might be caused by a version conflict between libraries shipped by MATLAB and the ones required by the Python package you are trying to use. More recent MATLAB releases are expected to have fewer such conflicts, so first try upgrading to a newer release, if possible.

Starting in MATLAB R2019b, you can also try the out-of-process execution mode while working with the Python interface in MATLAB. This runs the Python commands in a separate process and helps avoid potential library conflicts. You can use the following command to specify out-of-process execution mode.

pyenv("ExecutionMode","OutOfProcess")
