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

在使用**tf.keras.utils.plot_model(model, “mnist_model.png”)**的时候报错
Failed to import pydot. You must install pydot and graphviz for pydotprint to work
环境:
系统:win10
tensorflow:2.2.0
python3.7
解决方法:

1.手动安装graphviz

  1. 从官网下载安装包 https://graphviz.org/_pages/Download/Download_windows.html
    Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work
    2.安装后将安装路径添加到系统环境变量

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

2.安装pydot,graphviz,pydotplus

pip install pydot
pip install graphviz
pip install pydotplus

注意:我在按照上面步骤后(没安装pydotplus),死活不行,最后安装了pydotplus就神奇的好了
