mindspore.mint.nn.functional.silu
==================================
.. py:function:: mindspore.mint.nn.functional.silu(input, inplace=False)
逐元素计算激活函数SiLUSigmoid Linear Unit。有时也被称作Swish函数。该激活函数定义为
.. math::
\text{SiLU}(x) = x * \sigma(x),
其中 :math:`x` 是输入的元素, :math:`\sigma(x)` 是Sigmoid函数。
.. math::
\text{sigma}(x_i) = \frac{1}{1 + \exp(-x_i)},

参数:
- **input** (Tensor) - `input` 即为上述公式中的 :math:`x`。数据类型为float16或float32的输入。
- **inplace** (bool, 可选) - 若为 ``True`` 则启用原地更新功能。默认值: ``False``
返回:
Tensor数据类型和shape与 `input` 的相同。
异常:
- **TypeError** - `input` 的数据类型既不是float16也不是float32。
