/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

（2）安装graphviz

brew install graphviz

3、模型可视化

from SSRNET_model import SSR_net
from keras.utils.vis_utils import plot_model

img_size = 64
stage_num = [3,3,3]
lambda_local = 1
lambda_d = 1
weight_file = 'ssrnet_3_3_3_64_morph2_age.h5'
all_file = 'ssrnet_3_3_3_64_morph2_age_all.h5'
model = SSR_net(img_size,stage_num, lambda_local, lambda_d)()
model.load_weights(weight_file)
model.save(all_file)

plot_model(model, to_file='model_ssrnet_all.jpg', show_shapes=True)
