Important caveats: lookback > 1 for the interpretable setting?

Hello! I get that one should set the horizon to at least 2, but I was wondering if that'd be true also for the lookback parameter. I get an error when instancing NBeatsModel() with lookback=1. Cheers --francesca

Thank you, will take a look at this.
