Using Prophet Forecast on more than one category

[queenvi]

Hi

Please can you assist. I managed to build a predictive model for 1 itemset, however I would like to build a forecast on about 800 items. How can I go about doing this?

For Prophet, you will always input table with 2 columns, one is time-series related date/datetimestamp and other is dependent variable. For 800 items, you will make separate datasets and predict them individually. Hope that serves the purpose.
Thanks!

HI, @queenvi I would suggest writing a function and passing through each dataset and then appending them together and using pandas melt to get your data back to something more usable. If you want more details on my approach, I'm happy to chat further!
