mindspore.ops.Sign
- class mindspore.ops.Sign[source]
Performs sign on the tensor element-wise.
\[sign(x) = \begin{cases} -1, &if\ x < 0 \cr 0, &if\ x = 0 \cr 1, &if\ x > 0\end{cases}\]- Inputs:
x (Tensor) - The input tensor of any dimension.
- Outputs:
Tensor, has the same shape and dtype as the x.
- Raises
TypeError – If x is not a Tensor.
- Supported Platforms:
Ascend
GPU
CPU
Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> x = Tensor(np.array([[2.0, 0.0, -1.0]]), mindspore.float32) >>> sign = ops.Sign() >>> output = sign(x) >>> print(output) [[ 1. 0. -1.]]
