It takes as input a list of tensors, all of the same shape, and returns a single tensor (also of the same shape).
layer_maximum(inputs, ...)A tensor, the element-wise maximum 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.
