log10¶
Log10 激活函数(逐元素计算底为 10 的对数)
\[\begin{split}\\Out=log_{10} x\\\end{split}\]
返回¶
Tensor,Log10 算子底为 10 对数输出,数据类型与输入一致。
代码示例¶
import paddle
# example 1: x is a float
x_i = paddle.to_tensor([[1.0], [10.0]])
res = paddle.log10(x_i) # [[0.], [1.0]]
# example 2: x is float32
x_i = paddle.full(shape=[1], fill_value=10, dtype='float32')
paddle.to_tensor(x_i)
res = paddle.log10(x_i)
print(res) # [1.0]
# example 3: x is float64
x_i = paddle.full(shape=[1], fill_value=10, dtype='float64')
paddle.to_tensor(x_i)
res = paddle.log10(x_i)
print(res) # [1.0]
