"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).

Best, Marius
