run_stat results are the same?

Use stat_ model gbrt to test ETTm1 , the test result is a horizontal line。I don't know the reason for this result? Could you give me some information？

I am not sure about the reason. But it looks like "Naive Repeat" is used instead of gbrt.

[Jeffrey-JDong]

thank you for your reply. But i am sure i used gbrt.

Sorry, I tried the code and got the same output as you.
I basically followed some tutorials to write gbrt. Since that part is not used in our paper, I didn't carefully check the implementation of gbrt. The implementation is in lines 98~99 of stats_model.py. I will try to fix it these days.
