mindspore.ops.Inv
=================
.. 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:**
Tensorshape和数据类型与 `x` 相同。
**异常:**
**TypeError** - `x` 的数据类型不是float16、float32或int32。
**支持平台:**
``Ascend``
**样例:**
>>> inv = ops.Inv()
>>> x = Tensor(np.array([0.25, 0.4, 0.31, 0.52]), mindspore.float32)
>>> output = inv(x)
>>> print(output)
