Input tensors to a Model must be Keras tensors. Found:
Tensor("my_layer/Identity:0", shape=(?, 10, 1152, 16), dtype=float32)
(missing Keras metadata).

嗨，我在尝试将一个层的中间变量用作并行网络的输入时遇到此错误 . 这样一层的中间变量将输入到另一个网络 .

def call(self, inputs,  training=None):
    inputs_expand = K.expand_dims(inputs, 1)
    tensor_b = K.tile(inputs_expand, [1, 16, 1, 1])
    tensor_a = K.map_fn(lambda x: K.batch_dot(x, self.Weights, [2, 3]), elems=tensor_b)
    # I need this tensor_a
    # I tried many things but ended putting it to member variable.
    self.tensor_a = K.identity(inputs_hat)
    ....

在尝试构建并行模型时，我这样做

a_model = models.Model([my_layer.tensor_a],[my_layer.c])

我找不到任何解决这个问题的好办法？怎么能把张量变成 K.tensor ??
