mindspore.ops.Erf
- class mindspore.ops.Erf[source]
Computes the Gauss error function of x element-wise.
\[erf(x)=\frac{2} {\sqrt{\pi}} \int\limits_0^{x} e^{-t^{2}} dt\]- Inputs:
x (Tensor) - The input tensor. The data type must be float16 or float32. \((N,*)\) where \(*\) means, any number of additional dimensions, its rank should less than 8.
- Outputs:
Tensor, has the same shape and dtype as the x.
- Raises
TypeError – If dtype of x is neither float16 nor float32.
- Supported Platforms:
Ascend
GPU
Examples
>>> x = Tensor(np.array([-1, 0, 1, 2, 3]), mindspore.float32) >>> erf = ops.Erf() >>> output = erf(x) >>> print(output) [-0.8427168 0. 0.8427168 0.99530876 0.99997765]
