Python process terminated unexpectedly after snapping 100-150 photos

Hey All

Basically as the title suggests, I am using MATLAB to call a opython function that snaps raw images and creates plots, however, when I snap close to 100-150 photos I tend to get an error that says process terminated unexpectedly. Any Sort of help would be much appreciated!

Oh sorry I meant like the process I’m soing requires image analysis

Hi @Bera,

There may be a runtime dependency conflict between MATLAB and Python.

In general, using out-of-process execution mode will avoid these conflicts. For this reason, using out-of-process mode is the best practice when using the Python Interface. You can use the “pyenv” command during App start-up to run in out-of-process mode.

>> pyenv("Version","<path to python executable>", "ExecutionMode", "OutOfProcess")

You can refer to the following link to know more about adding ‘Startup Tasks and Input Arguments in App Designer’:

Also, you may go through the following MathWorks Documentations for valuable insights about using the Python Interface in MATLAB:

• Configure Your System to Use Python: https://www.mathworks.com/help/matlab/matlab_external/install-supported-python-implementation.html
• Reload Out-of-Process Python Interpreter: https://www.mathworks.com/help/matlab/matlab_external/reload-python-interpreter.html

I hope this helps.
