将TimeDistributed应用于Keras中的InceptionResnetV2时出错

我不知道为什么会出现此错误,但可以使用以下解决方法:

x=Input(shape=(10,299,299,3))

#join the steps dimension with the samples dimension, the model won't see a difference    
y=Lambda(lambda x: K.reshape(x,(-1,299,299,3)))(x)

#use a regular inception model
y = InceptionResNetV2(include_top=False,weights=None)(y)

#bring back the hidden steps dimension
y = Lambda(lambda x: K.reshape(x,(-1,10,8,8,1536)))(y)
