mindspore.Tensor.log1p

Tensor.log1p()[source]

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

x refers to self tensor.

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

Tensor, has the same shape as the x.

Raises

  • TypeError – If x is not a Tensor.

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

Supported Platforms:

Ascend GPU CPU

Examples

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