+ amax(a, axis=None, out=None, keepdims=_Null, initial=_Null)
+
+ Return the maximum of an array or maximum along an axis.
+
+ Parameters
+ ----------
+ a : ndarray
+ Input data.
+ Python native iterables not supported.
+
+ axis : None or int or tuple of ints, optional
+ Axis or axes along which to operate. By default, flattened input is
+ used.
+
+ Negative indices not supported.
+
+ out : ndarray, optional
+ Alternative output array in which to place the result. Must
+ be of the same shape and buffer length as the expected output.
+ See `doc.ufuncs` (Section "Output arguments") for more details.
+
+ keepdims : bool, optional
+ If this is set to True, the axes which are reduced are left
+ in the result as dimensions with size one. With this option,
+ the result will broadcast correctly against the input array.
+
+ If the default value is passed, then `keepdims` will not be
+ passed through to the `amax` method of sub-classes of
+ `ndarray`, however any non-default value will be. If the
+ sub-class' method does not implement `keepdims` any
+ exceptions will be raised.
+
+ initial : scalar, optional
+ The minimum value of an output element. Must be present to allow
+ computation on empty slice.
+
+ Not supported yet.
Review comment:
Actually there's one input supported, you can pass `None` and this operator
will still function.
