Thanks for the explanation! I was already playing with the compression. Best, F. On 8 Jul 2014 15:23, "Tiago de Paula Peixoto" <tiago@skewed.de> wrote:

Hi guys, when saving a graph with .save(), I understood that float are represented in hexadecimal exponentiation format. I was wondering the reason for that.
The hexadecimal format is to guarantee exact representation, so that you load exactly the same number you saved, without any loss. This is not possible with a decimal format.
The thing behind my question is that I built a graph with 5M vertices and 50M edges so storing it as an XML file leads to a 5GB one. So, if I can find a way to reduce the size, I will be very happy.
Just use gzip or bzip2.
Note that in graph-tool you can save directly in a compressed format by doing:
g.save("graph.xml.gz") # for gzip
or
g.save("graph.xml.bz2") # for bzip2
The same thing works for load.
This should lead to a strong reduction of your file size.
Best, Tiago
