    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.
     
    Starting in MATLAB R2019b, you can 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")
    Please refer to the documentation link below to learn more about this.
