For example, if there is a relationship transaction.session_id -> sessions.id and we are calculating a feature transactions: sessions.SUM(transactions.value) any rows for which there is no corresponding session should be given the default value of 0 instead of NaN.

Of course this should not normally occur, but when it does it seems more reasonable to use the default_value.

When there are only categoricals values Golden Featuers are not created. But there are still some models tried with Golden Features. This produces following error:

Golden Features not created due to error (please check errors.md).
Traceback (most recent call last):
