keras编写代码，dense层维度多出一维，求大佬解疑答惑
轴承故障的一维数据诊断和分类
我原先用TensorFlow编写的空洞门卷积代码，然后接了两个双向LSTM层和两个dense层，是可以运行程序的，为了出图比较方便，用Keras重新编写了我的代码。其中空洞门卷积是我自己编写的代码，TensorFlow版本如下：

    def conv1d_block(self, x, filters, kernel_size, dr, pd='SAME',name="name"):"""gated dilation conv1d layer"""glu = tf.sigmoid(v1d(x, filters, kernel_size, dilation_rate=dr, padding=pd))print('glu=',glu)conv = tf.tanh(v1d(x, filters, kernel_size, dilation_rate=dr, padding=pd))print('conv=',conv)conv3 = v1d(x, filters, kernel_size, dilation_rate=dr, padding=pd)cog = tf.multiply(conv, glu)cog1 = tf.multiply(1-glu, conv3)outputs = tf.add(cog, cog1)print('outputs=',outputs)return outputs

然后用Keras编写的代码如下：

def conv1d_block(input,filters, kernerl_size, strides, conv_padding,dr,name ):"""gated dilation conv1d layer"""glu =Conv1D(filters=filters, kernel_size=kernerl_size, strides=strides,padding=conv_padding,dilation_rate=dr )(input)glu=k.sigmoid(glu)print('glu=',glu)conv = Conv1D(filters=filters, kernel_size=kernerl_size, strides=strides,padding=conv_padding,dilation_rate=dr )(input)conv=k.tanh(conv)print('conv=',conv)conv3 = Conv1D(filters=filters, kernel_size=kernerl_size, strides=strides,padding=conv_padding,dilation_rate=dr )(input)weight_1 = Lambda(lambda x: x * 0.8)weight_2 = Lambda(lambda x: x * 0.2)weight_gru1 = weight_1(conv)weight_gru2 = weight_2(glu)weight_gru3 = weight_1(1-glu)weight_gru4 = weight_2(conv3)cog = Multiply()([weight_gru1, weight_gru2])cog1 = Multiply()([weight_gru3, weight_gru4])outputs = Add()([cog, cog1])print('outputs=',outputs)return outputs

print的时候Keras的输出是：

'''inputs_01 (?, 1200, 1)
glu= Tensor("Sigmoid:0", shape=(?, 1200, 16), dtype=float32)
conv= Tensor("Tanh:0", shape=(?, 1200, 16), dtype=float32)
outputs= Tensor("add_1/add:0", shape=(?, 1200, 16), dtype=float32)
glu= Tensor("Sigmoid_1:0", shape=(?, 1200, 16), dtype=float32)
conv= Tensor("Tanh_1:0", shape=(?, 1200, 16), dtype=float32)

outputs= Tensor("add_4/add:0", shape=(?, 1200, 16), dtype=float32)

dense1 Tensor("Dense1/Relu:0", shape=(?, 1200, 200, 200), dtype=float32)

TensorFlow的输出为：

input_shape= (1200,)
glu= Tensor("Sigmoid:0", shape=(?, 1, 16), dtype=float32)
conv= Tensor("Tanh:0", shape=(?, 1, 16), dtype=float32)
outputs= Tensor("Add:0", shape=(?, 1, 16), dtype=float32)
cov1 (?, 1, 16)
glu= Tensor("Sigmoid_1:0", shape=(?, 1, 16), dtype=float32)
conv= Tensor("Tanh_1:0", shape=(?, 1, 16), dtype=float32)
outputs= Tensor("Add_1:0", shape=(?, 1, 16), dtype=float32)
cov2 (?, 1, 16)
glu= Tensor("Sigmoid_2:0", shape=(?, 1, 16), dtype=float32)
conv= Tensor("Tanh_2:0", shape=(?, 1, 16), dtype=float32)
outputs= Tensor("Add_2:0", shape=(?, 1, 16), dtype=float32)
cov3 (?, 1, 16)
glu= Tensor("Sigmoid_3:0", shape=(?, 1, 16), dtype=float32)
conv= Tensor("Tanh_3:0", shape=(?, 1, 16), dtype=float32)
layer_output (?, 200)
(?, 10)
self.layer_final_output Tensor("dense2/BiasAdd:0", shape=(?, 10), dtype=float32)

TensorFlow的dense层输出就只有一个维度，但是Keras变成了两维，多出的一维是input的长度，而且进行Keras尽力model的时候运行时，出现了如下错误：

Traceback (most recent call last):File "D:/1111/NEW Train/Gru-train/Keras-GRU.py", line 151, in <module>model = Model(inputs=inputs_01, outputs=Dense2)File "C:ProgramDataAnaconda3libsite-packageskeraslegacyinterfaces.py", line 91, in wrapperreturn func(*args, **kwargs)File "C:ProgramDataAnaconda3libsite-packageskerasenginenetwork.py", line 93, in __init__self._init_graph_network(*args, **kwargs)File "C:ProgramDataAnaconda3libsite-packageskerasenginenetwork.py", line 231, in _init_graph_networkself.inputs, self.outputs)File "C:ProgramDataAnaconda3libsite-packageskerasenginenetwork.py", line 1366, in _map_graph_networktensor_index=tensor_index)File "C:ProgramDataAnaconda3libsite-packageskerasenginenetwork.py", line 1353, in build_mapnode_index, tensor_index)File "C:ProgramDataAnaconda3libsite-packageskerasenginenetwork.py", line 1353, in build_mapnode_index, tensor_index)File "C:ProgramDataAnaconda3libsite-packageskerasenginenetwork.py", line 1353, in build_mapnode_index, tensor_index)[Previous line repeated 4 more times]File "C:ProgramDataAnaconda3libsite-packageskerasenginenetwork.py", line 1325, in build_mapnode = layer._inbound_nodes[node_index]
AttributeError: 'NoneType' object has no attribute '_inbound_nodes'

这个问题困扰了好多天，一直没有解决，不知道是我编写的这个代码块有问题还是中间哪出错了（Keras后面是普通的两个LSTM和两个dense层），还请大佬们答疑解惑，谢谢
