mindspore.ops.Log1p

class mindspore.ops.Log1p[source]

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

Inputs:

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 less than 8.

Outputs:

Tensor, has the same shape as the x.

Raises: TypeError – If dtype of x is neither float16 nor float32.

Supported Platforms:: Ascend GPU

Examples

>>> x = Tensor(np.array([1.0, 2.0, 4.0]), mindspore.float32)
>>> log1p = ops.Log1p()
>>> output = log1p(x)
>>> print(output)
