报错：

future_dates_poly = poly.transform(future_dates.reshape(-1, 1))

报错信息如下：

AttributeError                            Traceback (most recent call last)
~\AppData\Local\Temp/ipykernel_18888/3887574451.py in <module>
      4 future_dates = pd.date_range(start='2023-11-01', periods=30)  # 示例未来日期
      5 future_dates = (future_dates - start_date).days
----> 6 future_dates_poly = poly.transform(future_dates.reshape(-1, 1))
      7 predictions = model.predict(future_dates_poly)

AttributeError: 'Int64Index' object has no attribute 'reshape'

改为：

future_dates_poly = poly.transform(future_dates.values.reshape(-1, 1))
