python library and matlab sdk

Refer to GPT and own ideas, according to AttributeError: module 'EX_4' has no attribute 'initialize', probably because the initialize function is not defined in the EX_4 module. The problem may be caused by the failure to include the initialize function in the package, or the function name may have been renamed.

You can check to see if the initialize function is included in the EX_4 module. If it is not, you need to make sure it is included in the package. If so, the function name may have been renamed. You need to check to see if there is an alias that specifies the initialize function name when packaging.

If you are sure that the initialize function has been properly packaged and the function name has not been renamed, then you can try using dir(EX_4) to view all properties and methods included in the EX_4 module to ensure that the initialize function has been properly imported. If the initialize function does not appear on the list, you may need to repackage the code to fix the problem.

Try to change EX_4.initialize() to EX_4.EX_4.initialize_runtime(), i.e.

my_EX_4 = EX_4.EX_4.initialize_runtime()

This is because after compiling MATLAB code into a Python module using the MATLAB Compiler SDK, the name of the module is actually ex_4.ex_4, not simply EX_4. Therefore, you need to use EX_4.EX_4 to call the functions in the module.

If the problem still cannot be resolved, it is recommended to check the MATLAB Compiler SDK compiled module for any initialize functions, or to check the module documentation to determine the correct method to call.

According to your information, the problem appears in line 13 because the Python interpreter cannot find a property named 'initialize'. This may be due to one of the following reasons:

MATLAB Compiler SDK is not installed correctly.
Compiler options may not be specified correctly or incorrect when packing.
The version of Python may not be specified correctly or the Python environment may be incorrect when packaging.
The name of the Python package or the name of the module may not be set correctly when packaging.

To solve this problem, you can try the following steps:

Ensure that the MATLAB Compiler SDK is correctly installed and set up according to the documentation.
Checks that compiler options are specified correctly when packing, such as whether MATLAB functions are specified to include, and the name and type of the generated shared library.
Verify that the correct Python version and environment are specified when packaging, and check that the name of the package and the name of the module are set correctly.
Verify that the MATLAB function called in Python code is correct. You can try running the same MATLAB code using the MATLAB command window to verify that it works properly

The EX_4 module may not be imported correctly. Try adding this:

import os
import sys

# 将EX_4模块所在的目录添加到系统路径中
ex_4_path = os.path.abspath(os.path.join(os.path.dirname(__file__), 'EX_4'))
sys.path.append(ex_4_path)

Based on Monster group and GPT:
According to the error message, it appears that there is no 'initialize' property in the 'EX_4' module. This may be due to problems packaging into Python libraries. You can try to check that the packaging process is correct and ensure that the correct functions and modules are specified when packaging.

Also, note that Python version 3.9 is being used and some libraries may not be compatible with that version. If the problem persists, try lowering the Python version to 3.7 or 3.8 and retesting the code.
