new_tensor(data, dtype=None, device=None, requires_grad=False) -> Tensor

Returns a new Tensor with :attr:`data` as the tensor data.
By default, the returned Tensor has the same :class:`torch.dtype` and
:class:`torch.device` as this tensor.

.. warning::

    :func:`new_tensor` always copies :attr:`data`. If you have a Tensor
    ``data`` and want to avoid a copy, use :func:`torch.Tensor.requires_grad_`
    or :func:`torch.Tensor.detach`.
    If you have a numpy array and want to avoid a copy, use
    :func:`torch.from_numpy`.

.. warning::

    When data is a tensor `x`, :func:`new_tensor()` reads out 'the data' from whatever it is passed,
    and constructs a leaf variable. Therefore ``tensor.new_tensor(x)`` is equivalent to ``x.clone().detach()``
    and ``tensor.new_tensor(x, requires_grad=True)`` is equivalent to ``x.clone().detach().requires_grad_(True)``.
    The equivalents using ``clone()`` and ``detach()`` are recommended.

Args:
    data (array_like): The returned Tensor copies :attr:`data`.
    {dtype}
    {device}

align_as(other) -> Tensor

Permutes the dimensions of the :attr:`self` tensor to match the dimension order
in the :attr:`other` tensor, adding size-one dims for any new names.

This operation is useful for explicit broadcasting by names (see examples).

All of the dims of :attr:`self` must be named in order to use this method.
The resulting tensor is a view on the original tensor.

All dimension names of :attr:`self` must be present in ``other.names``.
:attr:`other` may contain named dimensions that are not in ``self.names``;
the output tensor has a size-one dimension for each of those new names.

To align a tensor to a specific order, use :meth:`~Tensor.align_to`.

Examples::

    # Example 1: Applying a mask
    >>> mask = torch.randint(2, [127, 128], dtype=torch.bool).refine_names('W', 'H')
    >>> imgs = torch.randn(32, 128, 127, 3, names=('N', 'H', 'W', 'C'))
    >>> imgs.masked_fill_(mask.align_as(imgs), 0)


    # Example 2: Applying a per-channel-scale
    >>> def scale_channels(input, scale):
    >>>    scale = scale.refine_names('C')
    >>>    return input * scale.align_as(input)

    >>> num_channels = 3
    >>> scale = torch.randn(num_channels, names=('C',))
    >>> imgs = torch.rand(32, 128, 128, num_channels, names=('N', 'H', 'W', 'C'))
    >>> more_imgs = torch.rand(32, num_channels, 128, 128, names=('N', 'C', 'H', 'W'))
    >>> videos = torch.randn(3, num_channels, 128, 128, 128, names=('N', 'C', 'H', 'W', 'D'))

    # scale_channels is agnostic to the dimension order of the input
    >>> scale_channels(imgs, scale)
    >>> scale_channels(more_imgs, scale)
    >>> scale_channels(videos, scale)

index_copy_(dim, index, tensor) -> Tensor

Copies the elements of :attr:`tensor` into the :attr:`self` tensor by selecting
the indices in the order given in :attr:`index`. For example, if ``dim == 0``
and ``index[i] == j``, then the ``i``\ th row of :attr:`tensor` is copied to the
``j``\ th row of :attr:`self`.

The :attr:`dim`\ th dimension of :attr:`tensor` must have the same size as the
length of :attr:`index` (which must be a vector), and all other dimensions must
match :attr:`self`, or an error will be raised.

.. note::
    If :attr:`index` contains duplicate entries, multiple elements from
    :attr:`tensor` will be copied to the same index of :attr:`self`. The result
    is nondeterministic since it depends on which copy occurs last.

Args:
    dim (int): dimension along which to index
    index (LongTensor): indices of :attr:`tensor` to select from
    tensor (Tensor): the tensor containing values to copy

Example::

    >>> x = torch.zeros(5, 3)
    >>> t = torch.tensor([[1, 2, 3], [4, 5, 6], [7, 8, 9]], dtype=torch.float)

scatter_(dim, index, src, reduce=None) -> Tensor

Writes all values from the tensor :attr:`src` into :attr:`self` at the indices
specified in the :attr:`index` tensor. For each value in :attr:`src`, its output
index is specified by its index in :attr:`src` for ``dimension != dim`` and by
the corresponding value in :attr:`index` for ``dimension = dim``.

For a 3-D tensor, :attr:`self` is updated as::

    self[index[i][j][k]][j][k] = src[i][j][k]  # if dim == 0
    self[i][index[i][j][k]][k] = src[i][j][k]  # if dim == 1
    self[i][j][index[i][j][k]] = src[i][j][k]  # if dim == 2

This is the reverse operation of the manner described in :meth:`~Tensor.gather`.

:attr:`self`, :attr:`index` and :attr:`src` (if it is a Tensor) should all have
the same number of dimensions. It is also required that
``index.size(d) <= src.size(d)`` for all dimensions ``d``, and that
``index.size(d) <= self.size(d)`` for all dimensions ``d != dim``.
Note that ``index`` and ``src`` do not broadcast.

Moreover, as for :meth:`~Tensor.gather`, the values of :attr:`index` must be
between ``0`` and ``self.size(dim) - 1`` inclusive.

.. warning::

    When indices are not unique, the behavior is non-deterministic (one of the
    values from ``src`` will be picked arbitrarily) and the gradient will be
    incorrect (it will be propagated to all locations in the source that
    correspond to the same index)!

.. note::

    The backward pass is implemented only for ``src.shape == index.shape``.

Additionally accepts an optional :attr:`reduce` argument that allows
specification of an optional reduction operation, which is applied to all
values in the tensor :attr:`src` into :attr:`self` at the indicies
specified in the :attr:`index`. For each value in :attr:`src`, the reduction
operation is applied to an index in :attr:`self` which is specified by
its index in :attr:`src` for ``dimension != dim`` and by the corresponding
value in :attr:`index` for ``dimension = dim``.

Given a 3-D tensor and reduction using the multiplication operation, :attr:`self`
is updated as::

    self[index[i][j][k]][j][k] *= src[i][j][k]  # if dim == 0
    self[i][index[i][j][k]][k] *= src[i][j][k]  # if dim == 1
    self[i][j][index[i][j][k]] *= src[i][j][k]  # if dim == 2

Reducing with the addition operation is the same as using
:meth:`~torch.Tensor.scatter_add_`.

Args:
    dim (int): the axis along which to index
    index (LongTensor): the indices of elements to scatter, can be either empty
        or of the same dimensionality as ``src``. When empty, the operation
        returns ``self`` unchanged.
    src (Tensor or float): the source element(s) to scatter.
    reduce (str, optional): reduction operation to apply, can be either
        ``'add'`` or ``'multiply'``.

Example::

    >>> src = torch.arange(1, 11).reshape((2, 5))
    >>> src
    tensor([[ 1,  2,  3,  4,  5],
            [ 6,  7,  8,  9, 10]])

If :attr:`source` is a :class:`~torch.Storage`, the method sets the underlying
storage, offset, size, and stride.

Args:
    source (Tensor or Storage): the tensor or storage to use
    storage_offset (int, optional): the offset in the storage
    size (torch.Size, optional): the desired size. Defaults to the size of the source.
    stride (tuple, optional): the desired stride. Defaults to C-contiguous strides.

to(*args, **kwargs) -> Tensor

Performs Tensor dtype and/or device conversion. A :class:`torch.dtype` and :class:`torch.device` are
inferred from the arguments of ``self.to(*args, **kwargs)``.

.. note::

    If the ``self`` Tensor already
    has the correct :class:`torch.dtype` and :class:`torch.device`, then ``self`` is returned.
    Otherwise, the returned tensor is a copy of ``self`` with the desired
    :class:`torch.dtype` and :class:`torch.device`.

Here are the ways to call ``to``:

.. function:: to(dtype, non_blocking=False, copy=False, memory_format=torch.preserve_format) -> Tensor

    Returns a Tensor with the specified :attr:`dtype`

    Args:
        {memory_format}

.. function:: to(device=None, dtype=None, non_blocking=False, copy=False, memory_format=torch.preserve_format) -> Tensor

    Returns a Tensor with the specified :attr:`device` and (optional)
    :attr:`dtype`. If :attr:`dtype` is ``None`` it is inferred to be ``self.dtype``.
    When :attr:`non_blocking`, tries to convert asynchronously with respect to
    the host if possible, e.g., converting a CPU Tensor with pinned memory to a
    CUDA Tensor.
    When :attr:`copy` is set, a new Tensor is created even when the Tensor
    already matches the desired conversion.

    Args:
        {memory_format}

.. function:: to(other, non_blocking=False, copy=False) -> Tensor

    Returns a Tensor with same :class:`torch.dtype` and :class:`torch.device` as
    the Tensor :attr:`other`. When :attr:`non_blocking`, tries to convert
    asynchronously with respect to the host if possible, e.g., converting a CPU
    Tensor with pinned memory to a CUDA Tensor.
    When :attr:`copy` is set, a new Tensor is created even when the Tensor
    already matches the desired conversion.

Example::

    >>> tensor = torch.randn(2, 2)  # Initially dtype=float32, device=cpu

view(*shape) -> Tensor

Returns a new tensor with the same data as the :attr:`self` tensor but of a
different :attr:`shape`.

The returned tensor shares the same data and must have the same number
of elements, but may have a different size. For a tensor to be viewed, the new
view size must be compatible with its original size and stride, i.e., each new
view dimension must either be a subspace of an original dimension, or only span
across original dimensions :math:`d, d+1, \dots, d+k` that satisfy the following
contiguity-like condition that :math:`\forall i = d, \dots, d+k-1`,

Otherwise, it will not be possible to view :attr:`self` tensor as :attr:`shape`
without copying it (e.g., via :meth:`contiguous`). When it is unclear whether a
:meth:`view` can be performed, it is advisable to use :meth:`reshape`, which
returns a view if the shapes are compatible, and copies (equivalent to calling
:meth:`contiguous`) otherwise.

that dimension.

Tensor can be also expanded to a larger number of dimensions, and the
new ones will be appended at the front. For the new dimensions, the
size cannot be set to -1.

Expanding a tensor does not allocate new memory, but only creates a
new view on the existing tensor where a dimension of size one is
expanded to a larger size by setting the ``stride`` to 0. Any dimension
of size 1 can be expanded to an arbitrary value without allocating new
memory.

Args:

.. warning::

    More than one element of an expanded tensor may refer to a single
