dbglvl choice for option does not give me debugging information

[zhiyuan8]

I really appreciate your help and reply! Thank you a lot in advance! I follow your manual and set:

  options = MetisOptions(ncuts=2, niter=100, dbglvl=1)
  edge_cost, METIS_partition = nxmetis.partition(G=METIS_graph, nparts=2, node_weight='weight', edge_weight='weight', options=options)

I also tried other dbglvl values, such as 2,4,8,16,32,64,128,256. Unfortunately, nothing is printed. I am doing a 1-step bisection partitioning and my graph has both edge and node weight. I need 'dbglvl' to show details of partitioning. Could you please let me know why dbglvl does not work as expected?

Thanks a lot!
