Hi all,

I'm trying to generate a Python Package and Build a Python Application in Windows 10, following the tutorial:

https://es.mathworks.com/help/compiler_sdk/gs/create-a-python-application-with-matlab-code.html

But i get the following error, when i try to initialize the generated package:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "E:\Ruben\gb2s\proyectos\RecLocutor_Alysis\Test\VGGVox-master\toPython\new\makesqr\__init__.py", line 305, in initialize
    return _pir.initialize_package()
  File "E:\Ruben\gb2s\proyectos\RecLocutor_Alysis\Test\VGGVox-master\toPython\new\makesqr\__init__.py", line 253, in initialize_package
    package_handle.initialize()
  File "C:\Program Files\MATLAB\R2018b\toolbox\compiler_sdk\pysdk_py\matlab_pysdk\runtime\deployablepackage.py", line 33, in initialize
    mcr_handle = self.__cppext_handle.startMatlabRuntimeInstance(self.__ctf_path)
SystemError: Bundle#24 start failed: Loading C:\Program Files\MATLAB\R2018b\bin\win64\microservices\mcljmiutils\mwmcljmiutils.dllfailed with error: No se puede encontrar el mÃ³dulo especificado.

I've tried also to follow steps in answer of this link (with some differences) but i get the same error:

https://es.mathworks.com/matlabcentral/answers/502272-how-to-export-a-function-as-a-python-package-and-use-it-in-python?s_tid=answers_rc1-2_p2_MLT

I really have no idea what to do next. I have looked at other similar questions but i have not yet had any success..

Thanks in advance.

Rubén

Hi Ruben,

Please close MATLAB, find "lmwmcljmiutils.dll", delete it(save a backup copy), and restart MATLAB.
