无法在 Python 中调用 keras 模块

Question

我正在研究 keras。我是基尔斯的新手。这是我用于创建电影矢量和用户矢量的代码。应用扁平化后，它给出空张量。

movie_input = keras.layers.Input(shape=[1])
movie_vec = keras.layers.Flatten()(keras.layers.Embedding(n_movies + 1, 32) 
(movie_input))
movie_vec = keras.layers.Dropout(0.5)(movie_vec)
print(movie_vec)
# Same thing for the users
user_input = keras.layers.Input(shape=[1])
user_vec = keras.layers.Flatten()(keras.layers.Embedding(n_users + 1, 32) 
(user_input))
user_vec = keras.layers.Dropout(0.5)(user_vec)
print(user_vec)
input_vecs = keras.layers.merge([movie_vec, user_vec], mode='concat')
nn = keras.layers.Dropout(0.5)(keras.layers.Dense(128, activation='relu')    (input_vecs))
nn = keras.layers.normalization.BatchNormalization()(nn)
nn = keras.layers.Dropout(0.5)(keras.layers.Dense(128, activation='relu')(nn))
nn = keras.layers.normalization.BatchNormalization()(nn)
nn = keras.layers.Dense(128, activation='relu')(nn)

它给了我这个错误

>TypeError                                 Traceback (most recent call last)

18 # Next, we join them all together and put them
19 # through a pretty standard deep learning architecture
20 input_vecs = keras.layers.merge([movie_vec, user_vec], mode='concat')
21 nn = keras.layers.Dropout(0.5)(keras.layers.Dense(128,activation='relu')(input_vecs))
22 nn = keras.layers.normalization.BatchNormalization()(nn)
>TypeError: 'module' object is not callable

Answer 1

使用 keras 2.1.5

keras.layers.merge 方法在其中可用

Answer 2

keras.layers.merge不是可调用的。它是一个模块。查看其文档
