How to use the sol.topology.provisioning.uniformTM function in SoL

def MaxFlow():
    # ==============
    # Let's generate some example data; SOL has some functions to help with that.
    # ==============
    # A complete topology
    topo = complete_topology(5)
    # ingress-egress pairs, between which the traffic will flow
    iePairs = [(0, 3)]
    # generate a traffic matrix, in this case, a uniform traffic matrix with a million flows
    trafficMatrix = provisioning.uniformTM(
        iePairs, 10 ** 6)
    # compute traffic classes. We will only have one class that encompasses all the traffic;
    # assume that each flow consumes 2000 units of bandwidth
    trafficClasses = generateTrafficClasses(iePairs, trafficMatrix, {'allTraffic': 1},
                                            {'allTraffic': 2000})
    # since our topology is "fake", provision our links and generate link capacities in our network
    linkcaps = provisioning.provision_links(topo, trafficClasses, 1)
    # these will be our link constraints: do not load links more than 50%
    linkConstrCaps = {(u, v): .5 for u, v in topo.links()}

    # Start our optimization.
    # SOL automatically takes care of the path generation, but it needs the topology, traffic classes, path predicate
