mindspore.Tensor.expm1

Tensor.expm1() → Tensor

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

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

Note

The input Tensor. \(x\) in the above formula.

Returns

Tensor, has the same shape as the self.

Raises

TypeError – If self is not a Tensor.

Supported Platforms:

Ascend GPU CPU
