load/save weights in lasagne network

loadsavelasagne.py

# Optionally, you could now dump the network weights to a file like this:
np.savez('model.npz', *lasagne.layers.get_all_param_values(network))
#
# And load them again later on like this:
with np.load('model.npz') as f:
    param_values = [f['arr_%d' % i] for i in range(len(f.files))]
lasagne.layers.set_all_param_values(network, param_values)
