Traceback error

edit

Hello,

I am new to Sage Math and new to this forum. Basically, I have written code to generate a specific graph on 10 vertices from its adjacency matrix. I am receiving an error (pasted below), but when my advisor runs the same exact code on his machine, he does not receive an error. I do not know how to resolve this situation. I've pasted my code below, and the error that I receive follows. Any insight would be much appreciated, and let me know if you need more details (e.g., information about the machine I'm using, operating system, etc.).

sage: M = Matrix([(0,0,1,0,1,1,1,0,1,1), (0,0,0,1,1,1,0,1,1,1), \
(1,0,0,1,1,1,1,0,0,0), (0,1,1,0,1,1,0,1,0,0), (1,1,1,1,0,1,0,0,1,0), \
(1,1,1,1,1,0,0,0,0,1), (1,0,1,0,0,0,0,1,1,1), (0,1,0,1,0,0,1,0,1,1), \
(1,1,0,0,1,0,1,1,0,1), (1,1,0,0,0,1,1,1,1,0)])
sage: M
[0 0 1 0 1 1 1 0 1 1]
[0 0 0 1 1 1 0 1 1 1]
[1 0 0 1 1 1 1 0 0 0]
[0 1 1 0 1 1 0 1 0 0]
[1 1 1 1 0 1 0 0 1 0]
[1 1 1 1 1 0 0 0 0 1]
[1 0 1 0 0 0 0 1 1 1]
[0 1 0 1 0 0 1 0 1 1]
[1 1 0 0 1 0 1 1 0 1]
[1 1 0 0 0 1 1 1 1 0]
sage: G = Graph(M); G
Graph on 10 vertices
sage: G.plot().show()

Here is the error.
