mindspore.ops.log1p
- mindspore.ops.log1p(x)[source]
Returns the natural logarithm of one plus the input tensor element-wise.
\[out_i = {log_e}(x_i + 1)\]- Parameters
x (Tensor) – The input tensor. With float16 or float32 data type. The value must be greater than -1. \((N,*)\) where \(*\) means, any number of additional dimensions, its rank should be less than 8.
- Returns
Tensor, has the same shape as the x.
- Raises

Examples
>>> x = Tensor(np.array([1.0, 2.0, 4.0]), mindspore.float32) >>> output = ops.log1p(x) >>> print(output) [0.6931472 1.0986123 1.609438 ]
