i solved it

i have to gunzip the file twice!

first you should download the file pgp.xml.gz from the link mentioned before

-gunzip pgp.xml.gz to pgp.xml
-rename pgp.xml to pgp.xml.gz
-gunzip pgp.xml.gz to pgp.xml

after finishing above 3 steps, you can run gt_bench.py to test performance

thanks

Subject: [graph-tool] unable to load pgp.xml

hi all, i am new to graph tool, and i encounter a problem

i got the performance test files from http://graph-tool.skewed.de/performance

when i run gt_bench.py, it shows

[zhaojun@fedora performance]$ python gt_bench.py 
Traceback (most recent call last):
  File "gt_bench.py", line 6, in <module>
    g = load_graph("pgp.xml")
  File "/usr/lib/python2.7/site-packages/graph_tool/__init__.py", line 2352, in load_graph
    g.load(file_name, fmt, ignore_vp, ignore_ep, ignore_gp)
  File "/usr/lib/python2.7/site-packages/graph_tool/__init__.py", line 1989, in load
    ignore_ep, ignore_gp)
IOError: error reading from file 'pgp.xml':parse error: on line 1, column 0: not well-formed (invalid token)

i have no idea whether it is something related with the formate of xml file or with the graph tool API i installed

thanks
