tensorflow - Keras:layers.Input 和 layers.InputLayer 有什么区别？

Question

我应该什么时候使用 Input我什么时候应该使用 InputLayer ?在 source code有一个描述，但我不确定它是什么意思。

输入层:

Layer to be used as an entry point into a graph. It can either wrap an existing tensor (pass an input_tensor argument) or create its a placeholder tensor (pass arguments input_shape or batch_input_shape as well as dtype).

输入:

Input() is used to instantiate a Keras tensor. A Keras tensor is a tensor object from the underlying backend (Theano or TensorFlow), which we augment with certain attributes that allow us to build a Keras model just by knowing the inputs and outputs of the model.

Answer 1

我想 InputLayer已与 Graph 模型一起弃用。我建议您使用 Input，正如 Keras 文档中的所有示例所示。
