log10

Documentation

treetensor.torch.log10(input, *args, **kwargs)

Returns a new tensor with the logarithm to the base 10 of the elements of input.

Examples:

>>> import torch
>>> import treetensor.torch as ttorch
>>> ttorch.log10(ttorch.tensor([-4.0, -1.0, 0, 2.0, 4.8, 8.0]))
tensor([   nan,    nan,   -inf, 0.3010, 0.6812, 0.9031])

>>> ttorch.log10(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]]},
... }))

Description From Torch v1.10.0+cu102

torch.log10(input, *, out=None) → Tensor

Returns a new tensor with the logarithm to the base 10 of the elements of input.

\[y_{i} = \log_{10} (x_{i})\]

Args:

input (Tensor): the input tensor.

Keyword args:

out (Tensor, optional): the output tensor.

Example:

>>> a = torch.rand(5)
>>> a
tensor([ 0.5224,  0.9354,  0.7257,  0.1301,  0.2251])


>>> torch.log10(a)
tensor([-0.2820, -0.0290, -0.1392, -0.8857, -0.6476])
