Hi all, In general which graph format is fastest when writing/reading graphs? I am also getting errors when I load pickled and cpickled graphs...That is something like:
"TypeError: No registered converter was able to produce a C++ rvalue of type std::string from this Python object of type unicode"
Cheers,
Anatol

I've never benchmarked this extensively, but I do believe that either graphml or gml should be the fastest.

"TypeError: No registered converter was able to produce a C++ rvalue of type std::string from this Python object of type unicode"
I'd need more information, such a very simple script where this happens... What python version are you using?
Cheers, Tiago

The script:

thanks for the fast reply

Ok, this looks like a bug. It works fine in Python 3, but I cannot test with Python 2.7 right now. Could you please put this in a ticket in the website, so that I don't forget to fix it?
Cheers, Tiago

This has been fixed now in the git version...
