torch.expm1

torch.expm1(input, out=None) → Tensor

Returns a new tensor with the exponential of the elements minus 1 of input.

$y_{i} = e^{x_{i}} - 1$

Parameters

• input (Tensor) – the input tensor.

• out (Tensor, optional) – the output tensor.

Example:

>>> torch.expm1(torch.tensor([0, math.log(2.)]))
tensor([ 0.,  1.])
