Thank you for reporting! You encountered this exception as there is no zone information in your node.csv. This caveat has been clearly documented in the tutorial.
"Note that read_network(load_demand=True) will automatically check OD connectivity which requires zone info to be specified in node.csv. Otherwise, you will get an exception stating NO VALID OD VOLUME!! DOUBLE CHECK YOUR demand.csv'"
It is a duplicate of Issue #21.
