Documentation

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

In treetensor, you can use ones_like to create a tree of tensors with all the same value of like another tree.

Example:

>>> import torch
>>> import treetensor.torch as ttorch
>>> ttorch.full_like(torch.randn(2, 3), 2.3)  # the same as torch.full_like(torch.randn(2, 3), 2.3)
tensor([[2.3000, 2.3000, 2.3000],
        [2.3000, 2.3000, 2.3000]])

>>> ttorch.full_like({
...     'a': torch.randn(2, 3),
...     'b': {'x': torch.randn(4, )},
... }, 2.3)
<Tensor 0x7ff363bb6cf8>
├── a --> tensor([[2.3000, 2.3000, 2.3000],
│                 [2.3000, 2.3000, 2.3000]])
└── b --> <Tensor 0x7ff363bb69e8>
    └── x --> tensor([2.3000, 2.3000, 2.3000, 2.3000])

Torch Version Related

This documentation is based on torch.full_like in torch v1.9.0+cu102. Its arguments’ arrangements depend on the version of pytorch you installed.

If some arguments listed here are not working properly, please check your pytorch’s version with the following command and find its documentation.

python -c 'import torch;print(torch.__version__)'

The arguments and keyword arguments supported in torch v1.9.0+cu102 is listed below.

Description From Torch v1.9.0+cu102

torch.full_like(input, fill_value, \*, dtype=None, layout=torch.strided, device=None, requires_grad=False, memory_format=torch.preserve_format) → Tensor

Returns a tensor with the same size as input filled with fill_value. torch.full_like(input, fill_value) is equivalent to torch.full(input.size(), fill_value, dtype=input.dtype, layout=input.layout, device=input.device).

Args:

input (Tensor): the size of input will determine size of the output tensor. fill_value: the number to fill the output tensor with.

Keyword args:

dtype (torch.dtype, optional): the desired data type of returned Tensor.

Default: if None, defaults to the dtype of input.

layout (torch.layout, optional): the desired layout of returned tensor.

Default: if None, defaults to the layout of input.

device (torch.device, optional): the desired device of returned tensor.

Default: if None, defaults to the device of input.

requires_grad (bool, optional): If autograd should record operations on the

returned tensor. Default: False.

memory_format (torch.memory_format, optional): the desired memory format of

returned Tensor. Default: torch.preserve_format.
