[pyclustering.nnet.sync] Crash in case of DYNAMIC structure

[annoviko]

Introduction When user-custom structure is needed, then crash happens in case of ccore=True.

Example:

amount_neurons = 8
network = sync_network(amount_neurons, type_conn=conn_type.DYNAMIC, ccore=True)

# build circle structure
for i in range(1, len(network)):
    network.set_connection(i - 1, i)
    network.set_connection(i, i - 1)

network.set_connection(0, amount_neurons - 1)
network.set_connection(amount_neurons - 1, 0)

# simulate
output_dynamic = network.simulate(1000, 1)

sync_visualizer.show_output_dynamic(output_dynamic)
sync_visualizer.show_order_parameter(output_dynamic)

Output:

Traceback (most recent call last):
