How can I configure the log level of DGL?

Hi, all.

I’m having trouble with the logging of dgl.

dmlc/dgl/blob/master/src/graph/transform/metis_partition_hetero.cc#L78

    
      
            NULL,    // The size of the vertices for computing
            // the total communication volume
            NULL,     // The weights of the edges
            &nparts,  // The number of partitions.
            NULL,     // the desired weight for each partition and constraint
            NULL,     // the allowed load imbalance tolerance
            options,  // the array of options
            &objval,  // the edge-cut or the total communication volume of
            // the partitioning solution
            part);
          LOG(INFO) << "Partition a graph with " << g->NumVertices(0) << " nodes and "
                    << g->NumEdges(0) << " edges into " << k << " parts and get "
                    << objval << " edge cuts";
          switch (ret) {
            case METIS_OK:
              return part_arr;
            case METIS_ERROR_INPUT:
              LOG(FATAL) << "Error in Metis partitioning: input error";
            case METIS_ERROR_MEMORY:
              LOG(FATAL) << "Error in Metis partitioning: cannot allocate memory";
            default:

I guess LOG(INFO) is from dmlc-core. However, I did not know which environment variable can I set to configure the log level.

Can anyone give me some suggestions?

I don’t think it’s configurable now. Is there any specific log you want to control?

Thanks for the quick response. I don’t want to see so much log if I have to partition graphs multiple times…orz
