以上为Pycharm中出现的错误信息提示
解决方法：
1. cmd进入windows 2. pip install pydot 3. pip install graphviz
4. 还需要安装graphviz软件：https://graphviz.gitlab.io/_pages/Download/Download_windows.html，然后下载graphviz-2.38.msi
5.记住自己的安装地址，配置环境变量：
6.检查graphviz是否安装成功，cmd进入windows命令行，输入命令：dot -version
7.最后一步，在自己需要允许的python模块中加入：
from keras.utils.vis_utils import plot_model #方便打印模型图片
import os
os.environ["PATH"] += os.pathsep +'D:/Program Files (x86)/Graphviz2.38/bin/'
-------------------------------------------------------------------------------------
打印下图的语句：
plot_model(model,to_file='model1.png',show_shapes=True)
