I have compiled a python package for a matlab function. But when i run the same by initializing the mcr instance in python i get the error below. I suspect that the startup.m script is not being called and hence Matlab is not able to find the .dll file. How can this be fixed ?

I get this error while executing the matlab function from a flask app. But it runs without any errors when executed through a standalone python script or through the interpreter.

PS: I have a feeling that if i somehow call startup.m in my main function then it should solve the problem.

This issue is potentially caused by spaces in the Windows "%temp%" directory path. Once your Windows "%temp%" directory path does not have a space, the script should be able to execute without error. Spaces in the Windows "%temp%" directory may be caused by spaces in the Windows username.

Here "C:\Program Files\" seems to contain a space character. Changing to a directory without the "space character" in the path might help resolve this issue.

This is a known issue and you can find a workaround in the following bug report:

Quick update. After reinstalling MATLAB, I'm still getting the same error. I created a Python Package using the compiler library, which I then import in the Python code. I first call initialize() and then I call the main function in the package. And that's when the error occurs. All relevant paths have no white spaces.

Caught "std::exception" Exception message is:
Unable to load bundle binary C:\MATLAB\R2020b\bin\win64\builtins\matlab_toolbox_general_builtins\mwwkspintrospect_builtinimpl.dll. Error: 127: state not recoverable
