dtypes for the scoring function

When generating the Python scoring function in MM, the default dtypes are set to 'object', as below:
input_array = pd.DataFrame([[LOAN, MORTDUE, VALUE, REASON, JOB, YOJ, DEROG, DELINQ, CLAGE, NINQ, CLNO, DEBTINC]], columns=["LOAN", "MORTDUE", "VALUE", "REASON", "JOB", "YOJ", "DEROG", "DELINQ", "CLAGE", "NINQ", "CLNO", "DEBTINC"], dtype=object)
However, classifiers such as lightgbm don't accept object dtypes. So we may get an error when scoring with lightgbm models in MM:
ValueError: DataFrame.dtypes for data must be int, float or bool. Did not expect the data types in the following fields: LOAN, MORTDUE, VALUE, REASON, JOB, YOJ, DEROG, DELINQ, CLAGE, NINQ, CLNO, DEBTINC
I don't know whether it is safe to set all dtypes to float or None when generating the scoring func.
