[BUG]: unable to rebuild the saved model from the saved file

[inferesu]

Description of the bug

I am working with this code and I am saving the model which I later want to load. The problem is that I get this error "Error loading model: 'CustomANFIS' object has no attribute '__get_strength_by_prod'". I might be missing something, because I don't have much experience.

Steps To Reproduce

1. Create a new model
2. Use save_model()
3. use load_model()
4. observe the results

Expected results: The model is successfully loaded
Actual results: Error loading model: 'CustomANFIS' object has no attribute '__get_strength_by_prod'

Reproducible with: 1.1.0

@inferesu , Can you show me your code? You are not suppose to use CustomANFIS class. That is internal class used for OOP programming only. You are suppose to use our provided wrapper classes "AnfisRegressor, AnfisClassifier , GdAnfisRegressor, GdAnfisClassifier , BioAnfisRegressor, BioAnfisClassifier"

Hey, thank you for the quick response, I am using GdAnfisRegressor but when loading the model it throws "CustomANFIS". I am attaching the simplified versions of my scripts:

Save_test.py

Load_test.py

Thank you!

@inferesu,
You are not using the right way. That is why the error ocurs. In both save and load functions. Use this instead:

    try:
        # Wrong way:
        # 1. Create a new, empty model object.
        model = GdAnfisRegressor()
        # 2. Use the library's dedicated function to load the saved model.
        # THIS IS THE LINE THAT WILL FAIL.
        model.load_model(MODEL_FILE)

        # This is the right way:
        cls = GdAnfisRegressor
        model = cls.load_model(load_path="", filename="bug_report_model.pkl")

Same as save model.

    try:
        # Wrong way:
        model.save_model(MODEL_FILE)
        print(f"Model config saved to '{MODEL_FILE}'")

        # This is the right way:
        model.save_model(save_path="", filename="bug_report_model.pkl")

Any you should save model as .pkl file.

Sorry to bother you again. Changed saving to this:

try:
      model.save_model(save_path=".", filename="bug_report_model.pkl")

And loading to this:

 try:
        cls = GdAnfisRegressor
        model = cls.load_model(load_path=".", filename="bug_report_model.pkl")

but I still get the same custom ANFIS error.

 Error Type: AttributeError
 Error Message: 'CustomANFIS' object has no attribute '__get_strength_by_prod'

I really appreciate your help on this. Sorry if I am missing something really obvious.
