Hi @Farshid Daryabor,

It looks like you are trying to run a Python script, "merge_profiles.py", from MATLAB but are encountering an issue with MATLAB not recognizing the Python module. Here are some steps you can take to troubleshoot and resolve the issue:

• Verify Python Environment Setup in MATLAB: Ensure MATLAB is configured to use the correct Python environment. You can check the current Python environment by executing:

>> pyenv

You may refer to the below documentation for more details:

• Ensure Correct Module Import: After setting the path, try importing the module in MATLAB. For more details on how to call user-defined Python Module, refer to the documentation: https://www.mathworks.com/help/matlab/matlab_external/call-user-defined-custom-module.html
• MATLAB and Python Compatibility: Make sure the Python version is compatible with your MATLAB version. Check the compatibility from the following link: https://www.mathworks.com/support/requirements/python-compatibility.html

I hope this helps!
