paddle / log1p
log1p¶
该OP计算Log1p（加一的自然对数）结果。
\[\begin{split}\\Out=ln(x+1)\\\end{split}\]
- 参数:
-
x (Tensor) – 指定输入为一个多维的Tensor。数据类型为float32，float64。
name (str，可选) – 该参数供开发人员打印调试信息时使用，具体用法请参见 Name ，默认值为None。
返回：Tensor, Log1p算子自然对数输出，数据类型，形状为输入一致
代码示例
import paddle
data = paddle.to_tensor([[0], [1]], dtype='float32')
res = paddle.log1p(data)
# [[0.], [0.6931472]]
