mindspore.nn.LeakyReLU
=======================
.. py:class:: mindspore.nn.LeakyReLU(alpha=0.2)
逐元素计算Leaky ReLU激活函数。
该激活函数定义如下:
.. math::
\text{leaky_relu}(x) = \begin{cases}x, &\text{if } x \geq 0; \cr
{\alpha} * x, &\text{otherwise.}\end{cases}
其中,:math:`\alpha` 表示 `alpha` 参数。

参数:
- **alpha** (`Union[int, float]`) - `x` 小于0时激活函数的斜率默认值 ``0.2``
输入:
- **x** Tensor - 计算LeakyReLU的任意维度的Tensor。
输出:
Tensor数据类型和shape与 `x` 相同。
异常:
- **TypeError** - `alpha` 不是浮点数或整数。
