Looking at the Capabilities (GenericObjectEditor window ->
Capabilities button), you can see that InfoGainAttributeEval cannot
handle numeric classes:
Class -- Binary class, Missing class values, Nominal class
Attributes -- Binary attributes, Date attributes, Empty nominal
attributes, Missing values, Nominal attributes, Numeric attributes,
Unary attributes

And your dataset has a numeric class (faminc_50).

You can use the NumericToNominal filter on the attributes that are
actually categorical rather than numeric ones:
https://weka.sourceforge.io/doc.dev/weka/filters/unsupervised/attribute/NumericToNominal.html

Then save your dataset as ARFF and use that from then on.
