mindspore.nn.SiLU
=============================
.. py:class:: mindspore.nn.SiLU
SiLU激活函数。
逐元素计算SiLU激活函数。
SiLU函数定义为
.. math::
\text{SiLU}(x) = x * \sigma(x),
其中 :math:`x_i` 是输入的元素, :math:`\sigma(x)` 是Sigmoid函数。
.. math::
\text{sigmoid}(x_i) = \frac{1}{1 + \exp(-x_i)},
关于SiLU的图例见 `SiLU <https://en.wikipedia.org/wiki/Activation_function#/media/File:Swish.svg>`_
输入:
- **x** (Tensor) - 数据类型为float16或float32的输入。任意维度的Tensor。
输出:
Tensor数据类型和shape与 `x` 的相同。
异常:
- **TypeError** - `x` 的数据类型既不是float16也不是float32。
