In igraph, the ID of a vertex is its “number”; what you are using is not a
vertex ID but a vertex _name_. As a consequence, the names have to be assigned
to the “name” vertex attribute and it will work nicely. Also note that you can
assign all the names at once, there is no need to do them in a for loop:
A.vs[“name”] = nodes_list
T.
