Keras问题总结

环境：Win10、Anaconda3、Tensorflow-gpu 1.5.0、Keras 2.1.6
1. ImportError: Failed to import pydot. Please install pydot. For example with pip install pydot.
正如错误信息所提示的那样，用pip安装pydot即可

pip install pydot

2. pydot failed to call GraphViz.Please install GraphViz (https://www.graphviz.org/) and ensure that its executables are in the $PATH.
在官网下载GraphViz，zip文件或者msi文件都可。这里给出msi文件的百度云链接

安装好graphviz，默认安装的位置：C:\Program Files (x86)\Graphviz2.38
把C:\Program Files (x86)\Graphviz2.38\bin添加进PATH环境变量，即可

我参考的原文地址链接：https://www.codesofinterest.com/2017/02/visualizing-model-structures-in-keras.html
3. D:\Anaconda3\lib\site-packages\keras\models.py:282: UserWarning: No training configuration found in save file: the model was not compiled. Compile it manually. warnings.warn(‘No training configuration found in save file: ‘)

这个问题我现在也还没有解决，但推论是Keras版本的问题。
