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 list of input tensors (at least 2). Can be missing.
Standard layer arguments (must be named).
A tensor, the element-wise maximum of the inputs. If inputs is
missing, a keras layer instance is returned.
