mindspore.ops.Expm1

class mindspore.ops.Expm1[source]

Returns exponential then minus 1 of a tensor element-wise.

\[out_i = e^{x_i} - 1\]

Inputs:

x (Tensor) - The input tensor. With float16 or float32 data type. \((N,*)\) where \(*\) means, any number of additional dimensions, its rank should be less than 8.

Outputs:

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([0.0, 1.0, 2.0, 4.0]), mindspore.float32)
>>> expm1 = ops.Expm1()
>>> output = expm1(x)
>>> print(output)
