Hi, when importing graph files do vertices/nodes keep there original
ID or are nodes reassigned a new int value?
If so what is the simplest method to find the new ID value?

the reason is that with

a = i.similarity_inverse_log_weighted(vertices=290000)

igraph.core.InternalError: Error at iterators.c:711: Cannot create
iterator, invalid vertex id, Invalid vertex id
