Hello again, Suppose my frequency of my data is daily and I want to forecast future 50 days ahead of today by model trained based on past data.

You just pass X containing the timestamps you want to forecast into the trained model and predict.

我使用1750~2015每个月的数据进行单变量预测训练，想预测未来一百年的数据 但是范围太大会报错显示OverflowError: Overflow in int64 addition，最多大概只能预测25年左右，请问有解决办法吗
