This warning indicates you are mixing gtk2 and gtk3. Just so you know, the import for gtk3 looks like:

    from gi.repository import Gtk

The equivalent for gtk2 looks like this:

    import gtk

I hope that can steer you in the right direction, cheers!

Hello all,

I am pretty new to graph-tool and trying it because of the fast speed. However, it seems that graph-tool cannot work together with mlab in mayavi.

I am basically planning to plot a 3D graph using mlab. But  when I import mlab from mayavi, the program always prints the following warning and then becomes frozen. I don't know why. Is it the problem of gtk?  I just want to use graph-tool data structure and algorithms
