self.inner.to_str()

I'm trying to implement a multi-variate, multiple-step model to forecast the day ahead electricity prices (h+1,h+2,...,h+24). I know how to do one forecast, but I'm confused with how to implement a multiple output approach where each forecast gives a vector of predictions for each hour in the day...
