after converting Radoop Nest process to In Database Nest process  while running python script output dataframe, is showing  polynomial type then I use to store the results in csv and then use csv to convert into nominal type but still getting the same error

Hi @DR01K, it looks like you might be using the Select Attributes (In Database) operator. Could you try the standard Select Attributes operator and see if that works?

Hey @DR01K, could you please explain what you're trying to to in the first place? Using write CSV inside a In Database Nest to change something into nominal seems like a strange workaround for something. Let's try to find a solution to your original problem.
