Replace missing value is not working

mansour · November 2023

Dear All,
I am running the following process, I have already added three replace missing operators, but still I receive the error of weight by information gain and other weight operators cannot handle missing values.
Any thoughts?

Hi @mansour,

I can't run your process, but I saw that you set roles for attributes before the missing values handling.

If you don't check the "include special attributes" into the Replace missing Values operator, you will have missing values in your dataset and problems with the next operators.

please check that.

Best,
Cesar

Dear @ceaperez
Many thanks for your reply and suggestions. I made it simple to see the error message. I checked "include special attributes" but didn't work.
Thanks.
This is the error log:
