Hi Rakesh,
The error message you are encountering suggests that the ‘imageAnalysisSample2.m’ file you are trying to convert into a Python package uses an input argument of a type that is not supported by MATLAB's Python package generation process. Specifically, it mentions that ‘obj’ is not supported for Sample Generation.
As a possible workaround, you can pass the argument as ‘structs’ or ‘cell arrays’ instead of ‘obj’.
For example, if you have a class instance, you can convert it to a ‘struct’ for the purposes of interfacing with Python as shown below:
% Example of converting an object to a struct
objStruct = struct(obj);
Kindly refer to the following MathWorks documentation to know more about the struct function:
I hope the information provided above is helpful.
