mindspore.ops.GeLU
==================
.. py:class:: mindspore.ops.GeLU(*args, **kwargs)
高斯误差线性单元激活函数Gaussian Error Linear Units activation function
`Gaussian Error Linear Units (GELUs) <https://arxiv.org/abs/1606.08415>`_ 描述了GeLU函数。
此外,也可以参考 `BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding <https://arxiv.org/abs/1810.04805>`_
GeLU函数定义如下
.. math::
\text{output} = 0.5 * x * (1 + tanh(x / \sqrt{2})),
其中 :math:`tanh` 是双曲正切函数。
**输入:**
- **x** (Tensor) - 用于计算GeLU函数的Tensor数据类型为float16或float32。
**输出:**
Tensor数据类型和shape与 `x` 的相同。
**异常:**
- **TypeError** - `x` 不是Tensor。
- **TypeError** - `x` 的数据类型既不是float16也不是float32。
**支持平台:**
``Ascend`` ``GPU`` ``CPU``
**样例:**
>>> x = Tensor(np.array([1.0, 2.0, 3.0]), mindspore.float32)
>>> gelu = ops.GeLU()
>>> result = gelu(x)
>>> print(result)
