pzmm.ImportModel.import_model failed with TypeError after updating from 1.10.0 to 1.10.1

Tái hiện lỗi với model_manager_register_sample_sklearn.ipynb được liên kết, sau đó đọc pzmm/import_model.py và pzmm/write_score_code.py, đặc biệt là ImportModel.import_model, ScoreCode.write_score_code và ScoreCode._binary_target. Được xem là hoàn tất khi lệnh gọi phân loại nhị phân được báo cáo sử dụng predict_proba hoàn tất thành công trên sasctl 1.10.1 mà không có TypeError.

Describe the issue
After updating sasctl to 1.10.1, I experienced TypeError when calling pzmm.ImportModel.import_model with the same code that used to work in 1.10.0.

To Reproduce
Steps or example code to reproduce the issue.

# STEP 5: Import model
pzmm.ScoreCode.score_code = ''
lreg = pzmm.ImportModel.import_model(model_files=model_path, model_prefix=model_prefix, project=project,
                                     input_data=X, predict_method=[model.predict_proba, [float, float]],
                                     score_metrics=score_metrics, overwrite_model=True,
                                     target_values=['0', '1'], model_file_name=model_prefix + ".pickle")

The rest of my sample code can be found here:
https://github.com/pulungw/sascode/blob/main/python/model_manager_register_sample_sklearn.ipynb
Which was based from this article:
https://blogs.sas.com/content/subconsciousmusings/2023/08/11/mlops-for-pirates-and-snakes/

Expected behavior
pzmm.ImportModel.import_model finished execution succesfully like in 1.10.0.
