Hello world! Property maps are really useful and I've come to love them! However, sometimes it's handy to convert them back to arrays (for example for plotting).
For vertex property maps that are scalar valued, we have the handy shortcut `.a` or the method `.get_array()`. However, these do not seem to work for vector valued vp's. Say for example that I'm storing the 2D coordinates of the vertices inside the vp `pos`. `g.vp.pos.a` returns `None`, and the way I typically convert this to an array is ``` print(g.vp.pos) # <VertexPropertyMap object with value type 'vector<double>', for Graph 0x7f02f04d34f0, at 0x7f0297d164f0> pos = np.array(list(g.vp.pos)) print(pos.shape) # (100, 2) ``` but I wonder if there is a better way to do this. What do other people use in this case? Rodrigo _______________________________________________ graph-tool mailing list graph-tool@skewed.de https://lists.skewed.de/mailman/listinfo/graph-tool
