mindspore.Tensor.max
- Tensor.max(axis=None, keepdims=False, initial=None, where=True)[source]
Return the maximum of a tensor or maximum along an axis.
- Parameters
axis (Union[None, int, list, tuple of ints], optional) – Axis or axes along which to operate. By default, flattened input is used. If this is a tuple of ints, the maximum is selected over multiple axes, instead of a single axis or all the axes as before. Default: None.
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. Default: False.
initial (scalar, optional) – The minimum value of an output element. Must be present to allow computation on empty slice. Default: None.
where (bool Tensor, optional) – A boolean tensor which is broadcasted to match the dimensions of array, and selects elements to include in the reduction. If non-default value is passed, initial must also be provided. Default: True.
- Returns
Tensor or scalar, maximum of input tensor. If axis is None, the result is a scalar value. If axis is given, the result is a tensor of dimension
self.ndim - 1
.- Raises
