Hello,
I hope you're well.
I like very much your handbook and real-world examples.
My issue is the following concerning the Chapter 11 - notebook_gold_forecast_arima.ipynb : in the paragraph 24th of "ARIMA/Training-Testing Split" : there is a problem of "AttributeError: 'Series' object has no attribute 'ix':

In : results_dict = arima_gridsearch_cv(new_df.log_series,cv_splits=5)

Out :
`********************
Iteration 1 of 5
TRAIN: [ 0 1 2 ... 2922 2923 2924] TEST: [2925 2926 2927 ... 5847 5848 5849]

-> 5139 return object.getattribute(self, name)
5140
5141 def setattr(self, name: str, value) -> None:

AttributeError: 'Series' object has no attribute 'ix'`

Actually, the attribute 'ix' is deprecated since latest Python versions. So, I replaced 'ix' with 'iloc' in the arima_utils.py file (function : arima_gridsearch_cv), but it has another problem. So, I am upset, I have no clue to fix the problem. Could you please send us the updated files related to the chapter 11 ? I thank you in advance.

Best Regards,
