ImportError: Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work.

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

下载graphviz-2.38.msi

5.记住自己的安装地址，配置环境变量：

记住自己的安装目标，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

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)

正确运行得到的图片
