when run pred_len =1，MSE MAE have gap with sota ，maybe need more setting or parameters？

[xiaojintesha2019]

have run with ETTh2 datasheet ，but find when pred_len =1，MSE/MAE only ~0.657/0.444
pred_len =12/24 can get sota .
maybe more setting or parameter to tuning？

Pred_len = 1 requires meticulous search for the number of super -cooked numbers, because optimization may not be unstable.
