similarity_flooding case where e[1].long_name=None in __get_attribute_tuple

Hi Valentine authors!

I am having trouble with a bug that seems to be coming from Valentine, but I am unsure:

• in similarity_flooding.py, is it expected that long_name may sometimes be None? (this is causing my experiments to crash)

• dumbish question: is it possible that column_name should be =e[0].long_name ?

    def __get_attribute_tuple(self, node):
        column_name = None
        if node in self.__graph1.nodes():
            for e in self.__graph1.out_edges(node):
                links = self.__graph1.get_edge_data(e[0], e[1])
                if links.get('label') == "name":


                    column_name = e[1].long_name  ##### LONG_NAME is None
                    
                   
        else:
            for e in self.__graph2.out_edges(node):
                links = self.__graph2.get_edge_data(e[0], e[1])
                if links.get('label') == "name":
                    column_name = e[1].long_name
        return column_name

Hi Christina,

Thank you for pointing out this issue! Could you please share with us the exact error message and/or the dataset pair that creates the error? I believe it has to do with nan values on a schema level, but would greatly help to reproduce it on our side to fix it!

Sorry I left on extended vacation the next day :) I will post an update later this week.
