Graph' object has no attribute 'node

[donkarlo]

When running example.py, just for testing, this happened

GrowingNeuralGas/gng.py", line 83, in fit_network
self.network.node[s_1]['error'] += spatial.distance.euclidean(observation, self.network.node[s_1]['vector'])**2
AttributeError: 'Graph' object has no attribute 'node

The same issue. It seems gng is incompatible with newest networkx

change "node" to "nodes", such as "self.network.nodes[s_1]['error'] += spatial.distance.euclidean(observation, self.network.nodes[s_1]['vector'])**2"
