ARIMA operator returning attribute does not exist in RM studio

Hi all,

I have the Temp attribute in the data set but ARIMA can't recognize it and returns attribute does not exist. When I save the data as excel file and then retrieve the same data as excel file instead of fetching from data base, ARIMA does not return that error. I also attached the excel file.

Could it be a UI problem and how to work around it?

OS : Ubuntu 18.04

RM studio : 9.5

data set : 2 regular attribute / 721 examples

Hi @Samir ,

the reason is your get page in the beginning. RapidMiner cannot know what attributes are available, and thus we are not able to propagate the metadata accordingly. The ARIMA operator thus does not know whats coming in and the drop downs are not populated. You can still run the process after typing in the right attribute. The warning can be neglected.

Hi,

can you please check if the Temp attribute is of type numerical? It needs to be to be recognised. To parse it you likely want to use the Parse Numbers operator.

Hi @mschmitz

Yes. I already used Parse Numbers operator to change Temp from Nominal to Numeric.

I did something and the process runs error free but ARIMA operator still has the yellow sign saying that Temp attribute is missing.

I didn't enter the Time series attribute and tried to run the process and I got a pop up saying required parameter missing. When I push FIX NOW a dialog pops to set the parameter and when I enter the attribute there, I no longer get the initial error.

Also when I use the drop down menu to set a parameter, often there's nothing there although all operators are connected but again sometimes without any change I see the attributes in the drop down menu.
