It takes as input a list of tensors, all of the same shape, and returns a single tensor (also of the same shape).
layer_average(inputs, ...)A tensor, the average of the inputs. If inputs is missing, a keras
layer instance is returned.
A input tensor, or list of input tensors. Can be missing.
Unnamed args are treated as additional inputs. Named arguments are passed on as standard layer arguments.
