paddle / sqrt
sqrt¶
-
paddle.sqrt( x, name=None ) ¶
计算输入的算数平方根。
\[out=\sqrt x=x^{1/2}\]
注解
请确保输入中的数值是非负数。
参数:
x (Tensor) - 支持任意维度的Tensor。数据类型为float32，float64或float16。
name (str，可选) – 具体用法请参见 Name ，一般无需设置，默认值为None。
返回：返回类型为Tensor， 数据类型同输入一致。
代码示例：
import paddle
x = paddle.to_tensor([0.0, 9.0, 36.0])
y = paddle.sqrt(x)
print(y) # y=[0., 3., 6.]
