mindspore.ops.log1p

mindspore.ops.log1p(input)[source]

Returns the natural logarithm of one plus the input tensor element-wise.

\[out_i = \{log_e}(input_i + 1)\]

Parameters: input (Tensor) – The input tensor. The value must be greater than -1.
Returns: Tensor, has the same shape as the input.
Raises: TypeError – If input 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([1.0, 2.0, 4.0]), mindspore.float32)
>>> output = ops.log1p(x)
>>> print(output)
