randint_like

Documentation

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

In treetensor, you can use randint_like to create a tree of tensors with numbers in an integer range.

Examples:

>>> import torch
>>> import treetensor.torch as ttorch
>>> ttorch.randint_like(torch.ones(2, 3), 10)  # the same as torch.randint_like(torch.ones(2, 3), 10)
tensor([[0., 5., 0.],
        [2., 0., 9.]])

>>> ttorch.randint_like({
...     'a': torch.ones(2, 3),
...     'b': {'x': torch.ones(4, )},
... }, 10)
<Tensor 0x7ff363bb6748>
├── a --> tensor([[3., 6., 1.],
│                 [8., 9., 5.]])
└── b --> <Tensor 0x7ff363bb6898>
    └── x --> tensor([4., 4., 7., 1.])

Description From Torch v1.9.0+cu102

torch.randint_like(input, low=0, high, \*, dtype=None, layout=torch.strided, device=None, requires_grad=False, memory_format=torch.preserve_format) → Tensor

Returns a tensor with the same shape as Tensor input filled with random integers generated uniformly between low (inclusive) and high (exclusive).

Args:

input (Tensor): the size of input will determine size of the output tensor. low (int, optional): Lowest integer to be drawn from the distribution. Default: 0. high (int): One above the highest integer to be drawn from the distribution.

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.
