[graph-tool] Gtk-ERROR while plotting a matrix

Hello all, I am trying to plot the matrix representation of inferred blocks. state = gt.minimize_blockmodel_dl(G, deg_corr=True) e = state.get_matrix() plt.matshow(e.todense()) However, this throws an error: (ipython:14458): Gtk-ERROR **: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported Trace/breakpoint trap (core dumped) I am not sure what is happening. Any help? Thank you Snehal -- Snehal Madhukar Shekatkar Pune India
