Whenever you are calling a layer on some input, you are creating a new tensor (the output of the layer), and you are adding a "node" to the layer, linking the input tensor to the output tensor. When you are calling the same layer multiple times, that layer owns multiple nodes indexed as 1, 2, 3. These functions enable you to retrieve various tensor properties of layers with multiple nodes.
get_input_at(object, node_index)get_output_at(object, node_index)
get_input_shape_at(object, node_index)
get_output_shape_at(object, node_index)
get_input_mask_at(object, node_index)
get_output_mask_at(object, node_index)
A tensor (or list of tensors if the layer has multiple inputs/outputs).
Layer or model object
Integer, index of the node from which to retrieve the
attribute. E.g. node_index = 1 will correspond to the first time the
layer was called.

get_config(),
get_weights(),
