mindspore.ops.expm1

mindspore.ops.expm1(input)[source]

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

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

Parameters

input (Tensor) – The input tensor with a dtype of float16 or float32.

Returns

Tensor, has the same shape as the input.

Raises

TypeError – If input is not a Tensor.
TypeError – If dtype of input 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)
>>> output = ops.expm1(x)
>>> print(output)
