Problems running hmetis

I'm trying to get hmetis to partition one of the graph files which I created, but I keep getting,

Empty Hyperedge # 10

What does it mean ? Is something wrong with my graph file ? It has around 8000 verticies and 40,000 edges (and the edges have weights).

RE: Please open an issue in

Please open an issue in flyspray and upload your hgraph.

RE: I am also getting another

I am also getting another error now while playing around with the arguments in hmetis.

it says "Cannot partition graph with 0 cells"

This is again coming for the same graph file. It has 8000 nodes where each node is connected to five other nodes. The weights are float values. Am I doing something wrong here ?
