    The error are occuring when I try run the "Predict Lemonade Sales."

  • Yutong, 

    I tried to do what you say and the errors is gone but when I deploy the server to Excel the result Predicted Sales is too high.

    One more question. Why when I use the box 'Normalize data' with method min/max for the columns "Price and Ranfall" the data of Price change to 0? 

    Again thank you for your help. 

    Regards, 

    Caio
