How to Visualise a CNN model using Python I am new to Deep Learning and have been trying to show a plot of the CNN architecture using Python in Google Colab. Besides importing the necessary libraries, I have noticed from other resource that normally, we would declare a model {model = sequential()}, and then model.add (Conv2d or MaxPool or Activation etc.) and for visualising, print(model.summary()).

However, I have developed the CNN architecture using the below code and struggling with generating a model print. Could anybody tell what I am missing here. Thanks

input = Input(shape=X.shape[1:])                                  # 154x154x3
x = Conv2D(12, (3, 3), padding='same', activation='relu')(input)  # 154x154x12
x = Conv2D(12, (2, 2), strides=(2, 2), activation='relu')(x)      # 77x77x12
x = Conv2D(16, (3, 3), padding='same', activation='relu')(x)      # 77x77x16
x = Conv2D(16, (2, 2), strides=(2, 2), activation='relu')(x)      # 38x38x16
x = Conv2D(24, (3, 3), padding='same', activation='relu')(x)      # 38x38x24
x = Conv2D(24, (2, 2), strides=(2, 2), activation='relu')(x)      # 19x19x24
x = Conv2D(32, (3, 3), padding='same', activation='relu')(x)      # 19x19x32
x = Conv2D(32, (2, 2), strides=(2, 2), activation='relu')(x)      # 9x9x32
x = Conv2D(48, (3, 3), padding='same', activation='relu')(x)      # 9x9x48
x = Conv2D(48, (2, 2), strides=(2, 2), activation='relu')(x)      # 4x4x48
x = Dropout(0.5)(x)                                               # 4x4x48
x = Conv2D(n_classes, (1, 1))(x)                                  # 4x4x62
x = GlobalAvgPool2D()(x)                                          # 62
output = Activation('softmax')(x)                                 # 62
Add this two lines below of your code.

from keras.models import Model
model = Model(inputs=input, outputs=output) 
print(model.summery)
