keras获得某一层或者某层权重的输出实例-创新互联

一个例子：

    print("Loading vgg19 weights...")
 
    vgg_model = VGG19(include_top=False, weights='imagenet')
 
    from_vgg = dict()  # 因为模型定义中的layer的名字与原始vgg名字不同，所以需要调整
    from_vgg['conv1_1'] = 'block1_conv1'
    from_vgg['conv1_2'] = 'block1_conv2'
    from_vgg['conv2_1'] = 'block2_conv1'
    from_vgg['conv2_2'] = 'block2_conv2'
    from_vgg['conv3_1'] = 'block3_conv1'
    from_vgg['conv3_2'] = 'block3_conv2'
    from_vgg['conv3_3'] = 'block3_conv3'
    from_vgg['conv3_4'] = 'block3_conv4'
    from_vgg['conv4_1'] = 'block4_conv1'
    from_vgg['conv4_2'] = 'block4_conv2'
 
    for layer in model.layers:
      if layer.name in from_vgg:
        vgg_layer_name = from_vgg[layer.name]
        layer.set_weights(vgg_model.get_layer(vgg_layer_name).get_weights())
        print("Loaded VGG19 layer: " + vgg_layer_name)
