keras 模型可视化

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

1：把以前下的 pydot 与 graphviz 删掉

2：到官网上重新下载 graphviz

3：重新安装 ，不要放在C盘，因为放在C盘启动graphviz需要权限

4：配置环境变量如下

5：都装好了

6:电脑重启一下（必不可少）

7：模型可视化

from keras.layers import Conv2D, MaxPool2D
from keras.layers import Dense, Flatten

model = Sequential()
model.add(Conv2D(32, kernel_size=(5,5), activation='relu', input_shape = (28 ,28,1)))
model.add(MaxPool2D(pool_size=(2,2), strides=(2,2)))
model.add(Conv2D(64, kernel_size=(5,5), activation='relu'))
model.add(MaxPool2D(pool_size=(2,2), strides=(2,2)))
model.add(Flatten())
model.add(Dense(1000, activation='relu'))
model.add(Dense(10, activation='softmax'))
model.summary()
plot_model(model, to_file="D:\\20keras\\3.png", show_shapes=True)
