感谢评论区提供的方案。
采用model.summary(),model.get_config()和for循环均可获得Keras的层名。
示例如下图
对于keras特定层的命名，只需在层内添加 name 即可
model.add(Activation('softmax',name='dense_1') ) # 注意 name 要放于函数内
#提取中间层
from keras.models import Model
import keras
layer_name = 'dense_1' #获取层的名称
intermediate_layer_model = Model(inputs=model.input,
outputs=model.get_layer(layer_name).output)#创建的新模型
intermediate_output = intermediate_layer_model.predict(X_test)
doc = open(r'C://Users//CCUT04//Desktop//1.txt','w')
for i in intermediate_output:
print(i)
print(i , file = doc)
doc.close()
补充知识：关于用keras提取NN中间layer输出

假设我网络层数是上面这个结构.
如果我想得到pooling的输出， keras上有两张方法。
intermediate_layer_model = Model(inputs=model.input,outputs=model.get_layer(str('global_average_pooling1d_1')).output)
#model.summary()
#model.get_layer(str('cropping1d_1'))
intermediate_output = intermediate_layer_model.predict(data)
data是你的输入所用的数据....
from keras import backend as K
get_11rd_layer_output = K.function([model.layers[0].input],
[model.layers[10].output])
layer_output = get_11rd_layer_output([data])[0]
我这里第10层是Pooling层.
这两个代码的output是一样的..
一般我看人用的都是第二个...
