|
|
|
|||
|
|
.. py:class:: mindspore.ops.Inv(*args, **kwargs)
|
|||
|
|
|
|||
|
|
按元素计算输入Tensor的倒数。
|
|||
|
|
|
|||
|
|
.. math::
|
|||
|
|
out_i = \frac{1}{x_{i} }
|
|||
|
|
|
|||
|
|
**输入：**
|
|||
|
|
|
|||
|
|
**x** (Tensor) - shape为 :math:`(N,*)` 的Tensor，其中 :math:`*` 表示任意的附加维度数。数据类型必须是float16、float32或int32。
|
|||
|
|
|
|||
|
|
**输出：**
|
|||
|
|
|
|||
|
|
Tensor，shape和数据类型与 `x` 相同。
|
|||
|
|
|
|||
|
|
**异常：**
|
|||
|
|
|
|||
|
|
**TypeError** - `x` 的数据类型不是float16、float32或int32。

>>> x = Tensor(np.array([0.25, 0.4, 0.31, 0.52]), mindspore.float32)
|
|||
|
|
>>> output = inv(x)
