Hello,

First of all, thank you for your paper and your code, it is a pleasure to work with it.

However, I have a question about the following line :

When I run it, this line does not seem to do anything more than edge_att = (att + att) / 2.
As a result, edge weights are different depending on the direction of the edge (0 to 1 != 1 to 0).
Have I missed anything?
