full
(*args, **kwargs)[source]¶ In
treetensor
, you can useones
to create a tree of tensors with the same value.Example:
>>> import torch >>> import treetensor.torch as ttorch >>> ttorch.full((2, 3), 2.3) # the same as torch.full((2, 3), 2.3) tensor([[2.3000, 2.3000, 2.3000], [2.3000, 2.3000, 2.3000]]) >>> ttorch.full({'a': (2, 3), 'b': {'x': (4, )}}, 2.3) <Tensor 0x7ff363bbc7f0> ├── a --> tensor([[2.3000, 2.3000, 2.3000], │ [2.3000, 2.3000, 2.3000]]) └── b --> <Tensor 0x7ff363bbc8d0> └── x --> tensor([2.3000, 2.3000, 2.3000, 2.3000])

(size, fill_value, *, out=None, dtype=None, layout=torch.strided, device=None, requires_grad=False) → Tensor¶ Creates a tensor of size
size
filled withfill_value
. The tensor’s dtype is inferred fromfill_value
.- Args:
- size (int…): a list, tuple, or
torch.Size
of integers defining the shape of the output tensor.
fill_value (Scalar): the value to fill the output tensor with.
- size (int…): a list, tuple, or
- Keyword args:
out (Tensor, optional): the output tensor. dtype (
torch.dtype
, optional): the desired data type of returned tensor.Default: if
None
, uses a global default (seetorch.set_default_tensor_type()
).- layout (
torch.layout
, optional): the desired layout of returned Tensor. Default:
torch.strided
.- device (
torch.device
, optional): the desired device of returned tensor. Default: if
None
, uses the current device for the default tensor type (seetorch.set_default_tensor_type()
).device
will be the CPU for CPU tensor types and the current CUDA device for CUDA tensor types.- requires_grad (bool, optional): If autograd should record operations on the
returned tensor. Default:
False
.

Example:
>>> torch.full((2, 3), 3.141592) tensor([[ 3.1416, 3.1416, 3.1416], [ 3.1416, 3.1416, 3.1416]])
