Could you do one with duplicate data where there’s more data for the same date? Getting an error while using asfreq function saying cannot reinfect duplicate axis

[@DataHeroes]

What do you mean more data for the same date?

[@anjanirashmithachinta8690]

@@DataHeroes suppose we have multiple Sales for multiple sku’S on the same date! While using asfreq it doesn’t recognize it as a daily date as there are reputation in the dates

[@DataHeroes]

@@anjanirashmithachinta8690 got it. Either create one column per sku or if you subset to create the model, then set the frequency after subsetting. I hope it works!

The Colab dataset cannot access

[@arvinjjj]

Why didn't you split the data into training and testing?

[@DataHeroes]

To keep the video very short. Just that :)
