treetensor.torch.sigmoid_(input)

In-place version of treetensor.torch.sigmoid().

Examples:

>>> import torch
>>> import treetensor.torch as ttorch
>>> t = ttorch.tensor([1.0, 2.0, -1.5])
>>> ttorch.sigmoid_(t)
>>> t
tensor([0.7311, 0.8808, 0.1824])

>>> t = ttorch.tensor({
...     'a': [1.0, 2.0, -1.5],
...     'b': {'x': [[0.5, 1.2], [-2.5, 0.25]]},
... })
>>> ttorch.sigmoid_(t)
>>> t
