"Data to Series - Error: No value series in input example set"

rosana

Hello everybody!

I have an Example Set with about 100 examples and 25 regular attributes.
I would like to convert every attribute data into a series, and to obtain de Fourier Transform of every series.

I have used the "Data to Series" Operator, but it says "Process failed. No value series in input example set"

What should I do?

Thank you very much!!
Best regards, Rosana

Hi Rosana,

as always please post your process setup. The devil is in the details...

For me, the following process works perfectly. For your usecase, you have to set the transformation_mode to "series_from_examples" (which is the default).

Hi Marius,

I'm including now the code... If I'm not wrong I understand that I should set "series from attributes" as I would like to have a serie for each attribute... ¿?

Thank you very much!!

No, you need series from examples. Just try it

Of course you have to loop your attributes and handle each attribute on its own, because when you create a series from examples, you end up with only one series from only one attribute. That attribute can be specified with the parameter.
