keras.models.load_model() 给出错误“ValueError: Got 0 输入方程“baik,baij->bakj”，期待 2”

问题描述

我的代码将批处理矩阵乘法“tf.einsum('baik,baij->bakj',q,k)/np.sqrt(dv)”作为其中的一部分。在训练模型后，我使用“model.save('./model')”保存它，现在我想加载该保存的模型。我这样试过 "model = keras.models.load_model('./model',compile=False,custom_objects={'f1': f1})" 。但它给出了下面的错误。为什么会发生这种情况。

这是我创建模型的方式：

def MultiHeadsAttModel(l=7*7,d=1024,dv=64,dout=1024,nv = 16 ):

v1 = Input(shape = (l,d))
q1 = Input(shape = (l,d))
k1 = Input(shape = (l,d))

v2 = Dense(dv*nv,activation = "relu")(v1)
q2 = Dense(dv*nv,activation = "relu")(q1)
k2 = Dense(dv*nv,activation = "relu")(k1)

v = Reshape([l,nv,dv])(v2)
q = Reshape([l,dv])(q2)
k = Reshape([l,dv])(k2)
att = tf.einsum('baik,k)/np.sqrt(dv) #batch matrix multiplication
att = Lambda(lambda x:  K.softmax(x),output_shape=(l,nv))(att)
out = tf.einsum('bajk,baik->baji',att,v)
out = Reshape([l,d])(out)
out = Add()([out,q1])

out = Dense(dout,activation = "relu")(out)

return  Model(inputs=[q1,k1,v1],outputs=out) 



   
def create_model(input_shape,output_classes):
     mobile = tf.keras.applications.mobilenet.MobileNet(weights='imagenet')
     x = mobile.layers[-6].input
    
     if True:
        x = Reshape([7*7,1024])(x)
        att = MultiHeadsAttModel(l=7*7,nv = 16 )
        x = att([x,x,x])
        x = Reshape([7,7,1024])(x)   
        x = Batchnormalization()(x)
