Determining data type in RapidMiner

Question

How it is possible to set attributes when we import data from a CSV file? I have set "y" as label but I can not run the process because Input Example set has no attributes. Is there anyone who can help me to solve it?

Answer 1

You can change the roles and types of the attributes in data set meta data information in the read csv parameters. But as mentioned before i would recommend running the import wizard!

Answer 2

I think another way of solving this problem is using Set Role operator on a pre-loaded dataset from CSV.
