你好，我在进行长时预测（long_term_forecast）时，发现预测结果与真实值相比有偏移的现象。
我的数据是月度数据，目的是使用过去3个月的值去预测未来1个月值，即1_month_ahead，然后重新划分训练集，使用过去3个月的值去预测未来2个月的值，但是我仍只预测一个值，即跳过了未来一个月的值。在这种方案下，我设置最大预测6个月，训练6次，得到6次结果。(代码中`seq_len=3…

Hi there, thanks for the excellent work. I wonder if the model is able to perform univariate forecasting with exogenous variables. It seems no to me at first glance. Any insights would be appreciated.…

Test过程中，如果设置了inverse为True，执行到下面的代码时
```
if test_data.scale and self.args.inverse:
outputs = test_data.inverse_transform(outputs)

会报错：ValueError: Found array with dim 3. No…
