Hi Shrijeet,

import igraph
newgraph = igraph.Graph()
Read_Adjacency is a static method of the Graph object, therefore you shouldn't call it on a Graph instance that you constructed in the second line. If you want to create a graph from an adjacency matrix stored in a file, you should do it as follows:

from igraph import *
g = Graph.Read_Adjacency("adjmat.txt")

It is even easier using the load() function:

from igraph import *
g = load("adjmat.txt", format="adjacency")

This works with igraph 0.5.1, so in case you are still getting error messages, please check the version number of your igraph installation:

import igraph
print igraph.__version__
