説明
Is your feature request related to a current problem? Please describe.
Yes.When using backtest() with a model trained with train and val future covariates, forgetting to pass the full future covariates again at backtest time results in an error (IndexError: index 1 is out of bounds for axis 0 with size 1.).
Describe proposed solution A better explanation or error message should be thrown as it is the case for "regular" historical forecasts.
Additional context Error currently thrown :
IndexError: index 1 is out of bounds for axis 0 with size 1.
