如何在pyclustering中保存SOM网络模型？

Question

模型SOM net不能通过pickle保存，Python抛出异常ValueError ctypes包含指针的对象不能被pickle。如何解决这个问题？你知道吗

Answer 1

问题在Py0.8.2中得到解决：

import pickle
from pyclustering.nnet.som import som, type_conn
from pyclustering.utils import read_sample
from pyclustering.samples.definitions import SIMPLE_SAMPLES

sample = read_sample(SIMPLE_SAMPLES.SAMPLE_SIMPLE1)
network = som(1, 2, type_conn.grid_four)
network.train(sample, 100)

dump_network = pickle.dumps(network)
network = pickle.loads(dump_network)
