Is there any limitation for network size in ciw?

[neetu5510]

I am trying to simulate a network using ciw but it always gives the error 'module' object is not callable'. Can you explain why? I am taking 2 class of customers and trying to simulate a 13 node network. Is there some limitation on number of nodes for the network?

Thanks @neetu5510
There is no limit on Network size, as long as it all fits in memory.

The error 'module' object is not callable' looks like a syntax error to me. Can you post the code?

I am trying this code:

Hi @neetu5510

Your problem is the line Q=ciw.simulation(N). ciw.simualtion is a module. You want the object, so you need Q=ciw.Simulation(N).

With this change it should run.

Hey..Thanks a lot...it worked..
