exp2¶

Documentation¶

treetensor.torch.exp2(input, *args, **kwargs)[source]¶

Computes the base two exponential function of input.

Examples:

>>> import torch
>>> import treetensor.torch as ttorch
>>> ttorch.exp2(ttorch.tensor([-4.0, -1.0, 0, 2.0, 4.8, 8.0]))
tensor([6.2500e-02, 5.0000e-01, 1.0000e+00, 4.0000e+00, 2.7858e+01, 2.5600e+02])

>>> ttorch.exp2(ttorch.tensor({
...     'a': [-4.0, -1.0, 0, 2.0, 4.8, 8.0],
...     'b': {'x': [[-2.0, 1.2, 0.25],
...                 [16.0, 3.75, -2.34]]},
... }))
