Forecasting on multivarite long dataframe

[ErikErsmark]

Hello. I want to do multivariate forecasting using Moirai, on a long multivariate dataframe (containing several time series), forecasting several variates at once, e.g., 2. I have a multivariate dataframe with several time series, and thus an 'item_id' column.

The examples in the notebook 'https://github.com/SalesforceAIResearch/uni2ts/blob/main/example/moirai_forecast_pandas.ipynb', show how to forecast on a long dataframe (dataframe with several time series) but univariate, and show how to forecast on a multivariate dataframe (data frame with several columns), but not several time series. It does not show the combination of the 2.

I tried myself to figure it out but to no success. Would anyone please show me a quick toy example.
