    addcdiv(input, tensor1, tensor2, *, value=1, out=None) -> Tensor
    
    Performs the element-wise division of :attr:`tensor1` by :attr:`tensor2`,
    multiplies the result by the scalar :attr:`value` and adds it to :attr:`input`.
    
    .. warning::
        Integer division with addcdiv is no longer supported, and in a future
        release addcdiv will perform a true division of tensor1 and tensor2.
        The historic addcdiv behavior can be implemented as
        (input + value * torch.trunc(tensor1 / tensor2)).to(input.dtype)
        for integer inputs and as (input + value * tensor1 / tensor2) for float inputs.
        The future addcdiv behavior is just the latter implementation:
        (input + value * tensor1 / tensor2), for all dtypes.

    arange(start=0, end, step=1, *, out=None, dtype=None, layout=torch.strided, device=None, requires_grad=False) -> Tensor
    
    Returns a 1-D tensor of size :math:`\left\lceil \frac{\text{end} - \text{start}}{\text{step}} \right\rceil`
    with values from the interval ``[start, end)`` taken with common difference
    :attr:`step` beginning from `start`.
    
    Note that non-integer :attr:`step` is subject to floating point rounding errors when
    comparing against :attr:`end`; to avoid inconsistency, we advise subtracting a small epsilon from :attr:`end`
    in such cases.
    
    .. math::
        \text{out}_{{i+1}} = \text{out}_{i} + \text{step}
    
    Args:
        start (Number): the starting value for the set of points. Default: ``0``.
        end (Number): the ending value for the set of points
        step (Number): the gap between each pair of adjacent points. Default: ``1``.
    
    Keyword args:
        out (Tensor, optional): the output tensor.
        dtype (:class:`torch.dtype`, optional): the desired data type of returned tensor.
            Default: if ``None``, uses a global default (see :func:`torch.set_default_dtype`). If `dtype` is not given, infer the data type from the other input
            arguments. If any of `start`, `end`, or `stop` are floating-point, the
            `dtype` is inferred to be the default dtype, see
            :meth:`~torch.get_default_dtype`. Otherwise, the `dtype` is inferred to
            be `torch.int64`.
        layout (:class:`torch.layout`, optional): the desired layout of returned Tensor.
            Default: ``torch.strided``.
        device (:class:`torch.device`, optional): the desired device of returned tensor.
            Default: if ``None``, uses the current device for the default tensor type
            (see :func:`torch.set_default_device`). :attr:`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``.

    r"""
    asarray(obj, *, dtype=None, device=None, copy=None, requires_grad=False) -> Tensor
    
    Converts :attr:`obj` to a tensor.
    
    :attr:`obj` can be one of:
    
    1. a tensor
    2. a NumPy array or a NumPy scalar
    3. a DLPack capsule
    4. an object that implements Python's buffer protocol
    5. a scalar
    6. a sequence of scalars
    
    When :attr:`obj` is a tensor, NumPy array, or DLPack capsule the returned tensor will,
    by default, not require a gradient, have the same datatype as :attr:`obj`, be on the
    same device, and share memory with it. These properties can be controlled with the
    :attr:`dtype`, :attr:`device`, :attr:`copy`, and :attr:`requires_grad` keyword arguments.
    If the returned tensor is of a different datatype, on a different device, or a copy is
    requested then it will not share its memory with :attr:`obj`. If :attr:`requires_grad`
    is ``True`` then the returned tensor will require a gradient, and if :attr:`obj` is
    also a tensor with an autograd history then the returned tensor will have the same history.
    
    When :attr:`obj` is not a tensor, NumPy array, or DLPack capsule but implements Python's
    buffer protocol then the buffer is interpreted as an array of bytes grouped according to
    the size of the datatype passed to the :attr:`dtype` keyword argument. (If no datatype is
    passed then the default floating point datatype is used, instead.) The returned tensor
    will have the specified datatype (or default floating point datatype if none is specified)
    and, by default, be on the CPU device and share memory with the buffer.
    
    When :attr:`obj` is a NumPy scalar, the returned tensor will be a 0-dimensional tensor on
    the CPU and that doesn't share its memory (i.e. ``copy=True``). By default datatype will
    be the PyTorch datatype corresponding to the NumPy's scalar's datatype.
    
    When :attr:`obj` is none of the above but a scalar, or a sequence of scalars then the
    returned tensor will, by default, infer its datatype from the scalar values, be on the
    current default device, and not share its memory.
    
    .. seealso::
    
        :func:`torch.tensor` creates a tensor that always copies the data from the input object.
        :func:`torch.from_numpy` creates a tensor that always shares memory from NumPy arrays.
        :func:`torch.frombuffer` creates a tensor that always shares memory from objects that
        implement the buffer protocol.
        :func:`torch.from_dlpack` creates a tensor that always shares memory from
        DLPack capsules.
    
    Args:
        obj (object): a tensor, NumPy array, DLPack Capsule, object that implements Python's
               buffer protocol, scalar, or sequence of scalars.
    
    Keyword args:
        dtype (:class:`torch.dtype`, optional): the datatype of the returned tensor.
               Default: ``None``, which causes the datatype of the returned tensor to be
               inferred from :attr:`obj`.
        copy (bool, optional): controls whether the returned tensor shares memory with :attr:`obj`.
               Default: ``None``, which causes the returned tensor to share memory with :attr:`obj`
               whenever possible. If ``True`` then the returned tensor does not share its memory.
               If ``False`` then the returned tensor shares its memory with :attr:`obj` and an
               error is thrown if it cannot.
        device (:class:`torch.device`, optional): the device of the returned tensor.
               Default: ``None``, which causes the device of :attr:`obj` to be used. Or, if
               :attr:`obj` is a Python sequence, the current default device will be used.
        requires_grad (bool, optional): whether the returned tensor requires grad.
               Default: ``False``, which causes the returned tensor not to require a gradient.
               If ``True``, then the returned tensor will require a gradient, and if :attr:`obj`
               is also a tensor with an autograd history then the returned tensor will have
               the same history.

    bucketize(input, boundaries, *, out_int32=False, right=False, out=None) -> Tensor
    
    Returns the indices of the buckets to which each value in the :attr:`input` belongs, where the
    boundaries of the buckets are set by :attr:`boundaries`. Return a new tensor with the same size
    as :attr:`input`. If :attr:`right` is False (default), then the left boundary is open. Note that
    this behavior is opposite the behavior of
    `numpy.digitize <https://docs.scipy.org/doc/numpy/reference/generated/numpy.digitize.html>`_.
    More formally, the returned index satisfies the following rules:
    
    .. list-table::
       :widths: 15 85
       :header-rows: 1

       * - True
         - ``boundaries[i-1] <= input[m][n]...[l][x] < boundaries[i]``
    
    Args:
        input (Tensor or Scalar): N-D tensor or a Scalar containing the search value(s).
        boundaries (Tensor): 1-D tensor, must contain a strictly increasing sequence, or the return value is undefined.
    
    Keyword args:
        out_int32 (bool, optional): indicate the output data type. torch.int32 if True, torch.int64 otherwise.
                                    Default value is False, i.e. default output data type is torch.int64.
        right (bool, optional): if False, return the first suitable location that is found. If True, return the
                                last such index. If no suitable index found, return 0 for non-numerical value
                                (eg. nan, inf) or the size of :attr:`boundaries` (one pass the last index).
                                In other words, if False, gets the lower bound index for each value in :attr:`input`
                                from :attr:`boundaries`. If True, gets the upper bound index instead.
                                Default value is False.
        out (Tensor, optional): the output tensor, must be the same size as :attr:`input` if provided.

        :func:`torch.tensor_split` a function that always returns exactly the specified number of chunks
    
    If the tensor size along the given dimension :attr:`dim` is divisible by :attr:`chunks`,
    all returned chunks will be the same size.
    If the tensor size along the given dimension :attr:`dim` is not divisible by :attr:`chunks`,
    all returned chunks will be the same size, except the last one.
    If such division is not possible, this function may return fewer
    than the specified number of chunks.
    
    Arguments:
        input (Tensor): the tensor to split
        chunks (int): number of chunks to return
        dim (int): dimension along which to split the tensor

    Estimates the covariance matrix of the variables given by the :attr:`input` matrix, where rows are
    the variables and columns are the observations.
    
    A covariance matrix is a square matrix giving the covariance of each pair of variables. The diagonal contains
    the variance of each variable (covariance of a variable with itself). By definition, if :attr:`input` represents
    a single variable (Scalar or 1D) then its variance is returned.
    
    The sample covariance of the variables :math:`x` and :math:`y` is given by:
    
    .. math::
        \text{cov}(x,y) = \frac{\sum^{N}_{i = 1}(x_{i} - \bar{x})(y_{i} - \bar{y})}{\max(0,~N~-~\delta N)}
    
    where :math:`\bar{x}` and :math:`\bar{y}` are the simple means of the :math:`x` and :math:`y` respectively, and
    :math:`\delta N` is the :attr:`correction`.
    
    If :attr:`fweights` and/or :attr:`aweights` are provided, the weighted covariance
    is calculated, which is given by:
    
    .. math::
        \text{cov}_w(x,y) = \frac{\sum^{N}_{i = 1}w_i(x_{i} - \mu_x^*)(y_{i} - \mu_y^*)}
        {\max(0,~\sum^{N}_{i = 1}w_i~-~\frac{\sum^{N}_{i = 1}w_ia_i}{\sum^{N}_{i = 1}w_i}~\delta N)}
    
    where :math:`w` denotes :attr:`fweights` or :attr:`aweights` (``f`` and ``a`` for brevity) based on whichever is
    provided, or :math:`w = f \times a` if both are provided, and
    :math:`\mu_x^* = \frac{\sum^{N}_{i = 1}w_ix_{i} }{\sum^{N}_{i = 1}w_i}` is the weighted mean of the variable. If not
    provided, ``f`` and/or ``a`` can be seen as a :math:`\mathbb{1}` vector of appropriate size.
    
    Args:
        input (Tensor): A 2D matrix containing multiple variables and observations, or a
            Scalar or 1D vector representing a single variable.
    
    Keyword Args:
        correction (int, optional): difference between the sample size and sample degrees of freedom.
            Defaults to Bessel's correction, ``correction = 1`` which returns the unbiased estimate,
            even if both :attr:`fweights` and :attr:`aweights` are specified. ``correction = 0``
            will return the simple average. Defaults to ``1``.
        fweights (tensor, optional): A Scalar or 1D tensor of observation vector frequencies representing the number of
            times each observation should be repeated. Its numel must equal the number of columns of :attr:`input`.
            Must have integral dtype. Ignored if ``None``. Defaults to ``None``.
        aweights (tensor, optional): A Scalar or 1D array of observation vector weights.
            These relative weights are typically large for observations considered "important" and smaller for
            observations considered less "important". Its numel must equal the number of columns of :attr:`input`.
            Must have floating point dtype. Ignored if ``None``. Defaults to ``None``.
    
    Returns:
        (Tensor) The covariance matrix of the variables.

    diag_embed(input, offset=0, dim1=-2, dim2=-1) -> Tensor
    
    Creates a tensor whose diagonals of certain 2D planes (specified by
    :attr:`dim1` and :attr:`dim2`) are filled by :attr:`input`.
    To facilitate creating batched diagonal matrices, the 2D planes formed by
    the last two dimensions of the returned tensor are chosen by default.
    
    The argument :attr:`offset` controls which diagonal to consider:
    
    - If :attr:`offset` = 0, it is the main diagonal.
    - If :attr:`offset` > 0, it is above the main diagonal.
    - If :attr:`offset` < 0, it is below the main diagonal.
    
    The size of the new matrix will be calculated to make the specified diagonal
    of the size of the last input dimension.
    Note that for :attr:`offset` other than :math:`0`, the order of :attr:`dim1`
    and :attr:`dim2` matters. Exchanging them is equivalent to changing the
    sign of :attr:`offset`.
    
    Applying :meth:`torch.diagonal` to the output of this function with
    the same arguments yields a matrix identical to input. However,
    :meth:`torch.diagonal` has different default dimensions, so those
    need to be explicitly specified.
    
    Args:
        input (Tensor): the input tensor. Must be at least 1-dimensional.
        offset (int, optional): which diagonal to consider. Default: 0
            (main diagonal).
        dim1 (int, optional): first dimension with respect to which to

    Supports :ref:`broadcasting to a common shape <broadcasting-semantics>`,
    :ref:`type promotion <type-promotion-doc>`, and integer, float, and complex inputs.
    Always promotes integer types to the default scalar type.
    
    Args:

        other (Tensor or Number): the divisor
    
    Keyword args:
        rounding_mode (str, optional): Type of rounding applied to the result:
    
            * None - default behavior. Performs no rounding and, if both :attr:`input` and
              :attr:`other` are integer types, promotes the inputs to the default scalar type.
              Equivalent to true division in Python (the ``/`` operator) and NumPy's ``np.true_divide``.
            * ``"trunc"`` - rounds the results of the division towards zero.
              Equivalent to C-style integer division.
            * ``"floor"`` - rounds the results of the division down.
              Equivalent to floor division in Python (the ``//`` operator) and NumPy's ``np.floor_divide``.
    
        out (Tensor, optional): the output tensor.

    gradient(input, *, spacing=1, dim=None, edge_order=1) -> List of Tensors
    
    Estimates the gradient of a function :math:`g : \mathbb{R}^n \rightarrow \mathbb{R}` in
    one or more dimensions using the `second-order accurate central differences method
    <https://www.ams.org/journals/mcom/1988-51-184/S0025-5718-1988-0935077-0/S0025-5718-1988-0935077-0.pdf>`_ and
    either first or second order estimates at the boundaries.
    
    The gradient of :math:`g` is estimated using samples. By default, when :attr:`spacing` is not
    specified, the samples are entirely described by :attr:`input`, and the mapping of input coordinates
    to an output is the same as the tensor's mapping of indices to values. For example, for a three-dimensional
    :attr:`input` the function described is :math:`g : \mathbb{R}^3 \rightarrow \mathbb{R}`, and
    :math:`g(1, 2, 3)\ == input[1, 2, 3]`.
    
    When :attr:`spacing` is specified, it modifies the relationship between :attr:`input` and input coordinates.
    This is detailed in the "Keyword Arguments" section below.
    
    The gradient is estimated by estimating each partial derivative of :math:`g` independently. This estimation is
    accurate if :math:`g` is in :math:`C^3` (it has at least 3 continuous derivatives), and the estimation can be
    improved by providing closer samples. Mathematically, the value at each interior point of a partial derivative
    is estimated using `Taylor's theorem with remainder <https://en.wikipedia.org/wiki/Taylor%27s_theorem>`_.
    Letting :math:`x` be an interior point with :math:`x-h_l` and :math:`x+h_r` be points neighboring
    it to the left and right respectively, :math:`f(x+h_r)` and :math:`f(x-h_l)` can be estimated using:
    
    .. math::
        \begin{aligned}
            f(x+h_r) = f(x) + h_r f'(x) + {h_r}^2  \frac{f''(x)}{2} + {h_r}^3 \frac{f'''(\xi_1)}{6}, \xi_1 \in (x, x+h_r) \\
            f(x-h_l) = f(x) - h_l f'(x) + {h_l}^2  \frac{f''(x)}{2} - {h_l}^3 \frac{f'''(\xi_2)}{6}, \xi_2 \in (x, x-h_l) \\
        \end{aligned}
    
    Using the fact that :math:`f \in C^3` and solving the linear system, we derive:
    
    .. math::
        f'(x) \approx \frac{ {h_l}^2 f(x+h_r) - {h_r}^2 f(x-h_l)
              + ({h_r}^2-{h_l}^2 ) f(x) }{ {h_r} {h_l}^2 + {h_r}^2 {h_l} }
    
    .. note::
        We estimate the gradient of functions in complex domain
        :math:`g : \mathbb{C}^n \rightarrow \mathbb{C}` in the same way.
    
    The value of each partial derivative at the boundary points is computed differently. See edge_order below.
    
    Args:
        input (``Tensor``): the tensor that represents the values of the function
    
    Keyword args:
        spacing (``scalar``, ``list of scalar``, ``list of Tensor``, optional): :attr:`spacing` can be used to modify
            how the :attr:`input` tensor's indices relate to sample coordinates. If :attr:`spacing` is a scalar then
            the indices are multiplied by the scalar to produce the coordinates. For example, if :attr:`spacing=2` the
            indices (1, 2, 3) become coordinates (2, 4, 6). If :attr:`spacing` is a list of scalars then the corresponding
            indices are multiplied. For example, if :attr:`spacing=(2, -1, 3)` the indices (1, 2, 3) become coordinates (2, -2, 9).
            Finally, if :attr:`spacing` is a list of one-dimensional tensors then each tensor specifies the coordinates for
            the corresponding dimension. For example, if the indices are (1, 2, 3) and the tensors are (t0, t1, t2), then
            the coordinates are (t0[1], t1[2], t2[3])
    
        dim (``int``, ``list of int``, optional): the dimension or dimensions to approximate the gradient over.  By default
            the partial  gradient in every dimension is computed. Note that when :attr:`dim` is  specified the elements of
            the :attr:`spacing` argument must correspond with the specified dims."

    to an output is the same as the tensor's mapping of indices to values. For example, for a three-dimensional
    :attr:`input` the function described is :math:`g : \mathbb{R}^3 \rightarrow \mathbb{R}`, and
    :math:`g(1, 2, 3)\ == input[1, 2, 3]`.
    
    When :attr:`spacing` is specified, it modifies the relationship between :attr:`input` and input coordinates.

    The gradient is estimated by estimating each partial derivative of :math:`g` independently. This estimation is

    Estimates the gradient of a function :math:`g : \mathbb{R}^n \rightarrow \mathbb{R}` in
    one or more dimensions using the `second-order accurate central differences method
    <https://www.ams.org/journals/mcom/1988-51-184/S0025-5718-1988-0935077-0/S0025-5718-1988-0935077-0.pdf>`_ and
    either first or second order estimates at the boundaries.
    
    The gradient of :math:`g` is estimated using samples. By default, when :attr:`spacing` is not
    specified, the samples are entirely described by :attr:`input`, and the mapping of input coordinates
    to an output is the same as the tensor's mapping of indices to values. For example, for a three-dimensional
    :attr:`input` the function described is :math:`g : \mathbb{R}^3 \rightarrow \mathbb{R}`, and
    :math:`g(1, 2, 3)\ == input[1, 2, 3]`.
    
    When :attr:`spacing` is specified, it modifies the relationship between :attr:`input` and input coordinates.
    This is detailed in the "Keyword Arguments" section below.
    
    The gradient is estimated by estimating each partial derivative of :math:`g` independently. This estimation is
    accurate if :math:`g` is in :math:`C^3` (it has at least 3 continuous derivatives), and the estimation can be
    improved by providing closer samples. Mathematically, the value at each interior point of a partial derivative
    is estimated using `Taylor's theorem with remainder <https://en.wikipedia.org/wiki/Taylor%27s_theorem>`_.
    Letting :math:`x` be an interior point with :math:`x-h_l` and :math:`x+h_r` be points neighboring
    it to the left and right respectively, :math:`f(x+h_r)` and :math:`f(x-h_l)` can be estimated using:
    
    .. math::
        \begin{aligned}
            f(x+h_r) = f(x) + h_r f'(x) + {h_r}^2  \frac{f''(x)}{2} + {h_r}^3 \frac{f'''(\xi_1)}{6}, \xi_1 \in (x, x+h_r) \\
            f(x-h_l) = f(x) - h_l f'(x) + {h_l}^2  \frac{f''(x)}{2} - {h_l}^3 \frac{f'''(\xi_2)}{6}, \xi_2 \in (x, x-h_l) \\
        \end{aligned}
    
    Using the fact that :math:`f \in C^3` and solving the linear system, we derive:
    
    .. math::
        f'(x) \approx \frac{ {h_l}^2 f(x+h_r) - {h_r}^2 f(x-h_l)
              + ({h_r}^2-{h_l}^2 ) f(x) }{ {h_r} {h_l}^2 + {h_r}^2 {h_l} }
    
    .. note::
        We estimate the gradient of functions in complex domain
        :math:`g : \mathbb{C}^n \rightarrow \mathbb{C}` in the same way.
    
    The value of each partial derivative at the boundary points is computed differently. See edge_order below.
    
    Args:
        input (``Tensor``): the tensor that represents the values of the function
    
    Keyword args:
        spacing (``scalar``, ``list of scalar``, ``list of Tensor``, optional): :attr:`spacing` can be used to modify
            how the :attr:`input` tensor's indices relate to sample coordinates. If :attr:`spacing` is a scalar then
            the indices are multiplied by the scalar to produce the coordinates. For example, if :attr:`spacing=2` the
            indices (1, 2, 3) become coordinates (2, 4, 6). If :attr:`spacing` is a list of scalars then the corresponding
            indices are multiplied. For example, if :attr:`spacing=(2, -1, 3)` the indices (1, 2, 3) become coordinates (2, -2, 9).
            Finally, if :attr:`spacing` is a list of one-dimensional tensors then each tensor specifies the coordinates for
            the corresponding dimension. For example, if the indices are (1, 2, 3) and the tensors are (t0, t1, t2), then
            the coordinates are (t0[1], t1[2], t2[3])

    gradient(input, *, spacing=1, dim=None, edge_order=1) -> List of Tensors
    
    Estimates the gradient of a function :math:`g : \mathbb{R}^n \rightarrow \mathbb{R}` in
    one or more dimensions using the `second-order accurate central differences method
    <https://www.ams.org/journals/mcom/1988-51-184/S0025-5718-1988-0935077-0/S0025-5718-1988-0935077-0.pdf>`_ and
    either first or second order estimates at the boundaries.
    
    The gradient of :math:`g` is estimated using samples. By default, when :attr:`spacing` is not
    specified, the samples are entirely described by :attr:`input`, and the mapping of input coordinates
    to an output is the same as the tensor's mapping of indices to values. For example, for a three-dimensional
    :attr:`input` the function described is :math:`g : \mathbb{R}^3 \rightarrow \mathbb{R}`, and
    :math:`g(1, 2, 3)\ == input[1, 2, 3]`.
    
    When :attr:`spacing` is specified, it modifies the relationship between :attr:`input` and input coordinates.
    This is detailed in the "Keyword Arguments" section below.
    
    The gradient is estimated by estimating each partial derivative of :math:`g` independently. This estimation is
    accurate if :math:`g` is in :math:`C^3` (it has at least 3 continuous derivatives), and the estimation can be
    improved by providing closer samples. Mathematically, the value at each interior point of a partial derivative
    is estimated using `Taylor's theorem with remainder <https://en.wikipedia.org/wiki/Taylor%27s_theorem>`_.
    Letting :math:`x` be an interior point with :math:`x-h_l` and :math:`x+h_r` be points neighboring
    it to the left and right respectively, :math:`f(x+h_r)` and :math:`f(x-h_l)` can be estimated using:
    
    .. math::
        \begin{aligned}
            f(x+h_r) = f(x) + h_r f'(x) + {h_r}^2  \frac{f''(x)}{2} + {h_r}^3 \frac{f'''(\xi_1)}{6}, \xi_1 \in (x, x+h_r) \\
            f(x-h_l) = f(x) - h_l f'(x) + {h_l}^2  \frac{f''(x)}{2} - {h_l}^3 \frac{f'''(\xi_2)}{6}, \xi_2 \in (x, x-h_l) \\
        \end{aligned}
    
    Using the fact that :math:`f \in C^3` and solving the linear system, we derive:
    
    .. math::
        f'(x) \approx \frac{ {h_l}^2 f(x+h_r) - {h_r}^2 f(x-h_l)
              + ({h_r}^2-{h_l}^2 ) f(x) }{ {h_r} {h_l}^2 + {h_r}^2 {h_l} }
    
    .. note::
        We estimate the gradient of functions in complex domain
        :math:`g : \mathbb{C}^n \rightarrow \mathbb{C}` in the same way.
    
    The value of each partial derivative at the boundary points is computed differently. See edge_order below.
    
    Args:
        input (``Tensor``): the tensor that represents the values of the function
    
    Keyword args:
        spacing (``scalar``, ``list of scalar``, ``list of Tensor``, optional): :attr:`spacing` can be used to modify
            how the :attr:`input` tensor's indices relate to sample coordinates. If :attr:`spacing` is a scalar then
            the indices are multiplied by the scalar to produce the coordinates. For example, if :attr:`spacing=2` the
            indices (1, 2, 3) become coordinates (2, 4, 6). If :attr:`spacing` is a list of scalars then the corresponding
            indices are multiplied. For example, if :attr:`spacing=(2, -1, 3)` the indices (1, 2, 3) become coordinates (2, -2, 9).
            Finally, if :attr:`spacing` is a list of one-dimensional tensors then each tensor specifies the coordinates for
            the corresponding dimension. For example, if the indices are (1, 2, 3) and the tensors are (t0, t1, t2), then
            the coordinates are (t0[1], t1[2], t2[3])
    
        dim (``int``, ``list of int``, optional): the dimension or dimensions to approximate the gradient over.  By default
            the partial  gradient in every dimension is computed. Note that when :attr:`dim` is  specified the elements of
            the :attr:`spacing` argument must correspond with the specified dims."
    
        edge_order (``int``, optional): 1 or 2, for `first-order
            <https://www.ams.org/journals/mcom/1988-51-184/S0025-5718-1988-0935077-0/S0025-5718-1988-0935077-0.pdf>`_ or

    Interprets the elements of an input tensor whose innermost dimension has size N

    N-dimensional bins and returns the number of points (or total weight) in each bin.
    
    :attr:`input` must be a tensor with at least 2 dimensions.
    If input has shape (M, N), each of its M rows defines a point in N-dimensional space.
    If input has three or more dimensions, all but the last dimension are flattened.
    
    Each dimension is independently associated with its own strictly increasing sequence
    of bin edges. Bin edges may be specified explicitly by passing a sequence of 1D
    tensors. Alternatively, bin edges may be constructed automatically by passing a
    sequence of integers specifying the number of equal-width bins in each dimension.
    
    For each N-dimensional point in input:
        - Each of its coordinates is binned independently among the bin edges
            corresponding to its dimension
        - Binning results are combined to identify the N-dimensional bin (if any)

                            tensor is passed, each N-dimensional coordinate in input
                            contributes its associated weight towards its bin's result.

    kron(input, other, *, out=None) -> Tensor
    
    Computes the Kronecker product, denoted by :math:`\otimes`, of :attr:`input` and :attr:`other`.
    
    If :attr:`input` is a :math:`(a_0 \times a_1 \times \dots \times a_n)` tensor and :attr:`other` is a
    :math:`(b_0 \times b_1 \times \dots \times b_n)` tensor, the result will be a
    :math:`(a_0*b_0 \times a_1*b_1 \times \dots \times a_n*b_n)` tensor with the following entries:
    
    .. math::
        (\text{input} \otimes \text{other})_{k_0, k_1, \dots, k_n} =
            \text{input}_{i_0, i_1, \dots, i_n} * \text{other}_{j_0, j_1, \dots, j_n},
    
    where :math:`k_t = i_t * b_t + j_t` for :math:`0 \leq t \leq n`.
    If one tensor has fewer dimensions than the other it is unsqueezed until it has the same number of dimensions.
    
    Supports real-valued and complex-valued inputs.
    
    .. note::
        This function generalizes the typical definition of the Kronecker product for two matrices to two tensors,
        as described above. When :attr:`input` is a :math:`(m \times n)` matrix and :attr:`other` is a
        :math:`(p \times q)` matrix, the result will be a :math:`(p*m \times q*n)` block matrix:

    r"""
    matmul(input, other, *, out=None) -> Tensor
    
    Matrix product of two tensors.
    
    The behavior depends on the dimensionality of the tensors as follows:
    
    - If both tensors are 1-dimensional, the dot product (scalar) is returned.
    - If both arguments are 2-dimensional, the matrix-matrix product is returned.
    - If the first argument is 1-dimensional and the second argument is 2-dimensional,
      a 1 is prepended to its dimension for the purpose of the matrix multiply.
      After the matrix multiply, the prepended dimension is removed.
    - If the first argument is 2-dimensional and the second argument is 1-dimensional,
      the matrix-vector product is returned.
    - If both arguments are at least 1-dimensional and at least one argument is
      N-dimensional (where N > 2), then a batched matrix multiply is returned.  If the first
      argument is 1-dimensional, a 1 is prepended to its dimension for the purpose of the
      batched matrix multiply and removed after.  If the second argument is 1-dimensional, a
      1 is appended to its dimension for the purpose of the batched matrix multiple and removed after.
      The non-matrix (i.e. batch) dimensions are :ref:`broadcasted <broadcasting-semantics>` (and thus
      must be broadcastable).  For example, if :attr:`input` is a
      :math:`(j \times 1 \times n \times n)` tensor and :attr:`other` is a :math:`(k \times n \times n)`
      tensor, :attr:`out` will be a :math:`(j \times k \times n \times n)` tensor.
    
      Note that the broadcasting logic only looks at the batch dimensions when determining if the inputs
      are broadcastable, and not the matrix dimensions. For example, if :attr:`input` is a
      :math:`(j \times 1 \times n \times m)` tensor and :attr:`other` is a :math:`(k \times m \times p)`
      tensor, these inputs are valid for broadcasting even though the final two dimensions (i.e. the
      matrix dimensions) are different. :attr:`out` will be a :math:`(j \times k \times n \times p)` tensor.
    
    This operation has support for arguments with :ref:`sparse layouts<sparse-docs>`. In particular the
    matrix-matrix (both arguments 2-dimensional) supports sparse arguments with the same restrictions
    as :func:`torch.mm`
    
    
    .. warning::
        Sparse support is a beta feature and some layout(s)/dtype/device combinations may not be supported,
        or may not have autograd support. If you notice missing functionality please
        open a feature request.
    
    This operator supports :ref:`TensorFloat32<tf32_on_ampere>`.
    
    On certain ROCm devices, when using float16 inputs this module will use :ref:`different precision<fp16_on_mi200>` for backward.
    
    .. note::
    
        The 1-dimensional dot product version of this function does not support an :attr:`out` parameter.

    Performs a matrix multiplication of the matrices :attr:`input` and :attr:`mat2`.
    
    If :attr:`input` is a :math:`(n \times m)` tensor, :attr:`mat2` is a
    :math:`(m \times p)` tensor, :attr:`out` will be a :math:`(n \times p)` tensor.
    
    .. note:: This function does not :ref:`broadcast <broadcasting-semantics>`.
              For broadcasting matrix products, see :func:`torch.matmul`.
    
    Supports strided and sparse 2-D tensors as inputs, autograd with
    respect to strided inputs.
    
    This operation has support for arguments with :ref:`sparse layouts<sparse-docs>`.
    If :attr:`out` is provided it's layout will be used. Otherwise, the result
    layout will be deduced from that of :attr:`input`.

    This operator supports :ref:`TensorFloat32<tf32_on_ampere>`.
    
    On certain ROCm devices, when using float16 inputs this module will use :ref:`different precision<fp16_on_mi200>` for backward.

    multinomial(input, num_samples, replacement=False, *, generator=None, out=None) -> LongTensor
    
    Returns a tensor where each row contains :attr:`num_samples` indices sampled
    from the multinomial (a stricter definition would be multivariate,
    refer to torch.distributions.multinomial.Multinomial for more details)
    probability distribution located in the corresponding row
    of tensor :attr:`input`.
    
    .. note::
        The rows of :attr:`input` do not need to sum to one (in which case we use
        the values as weights), but must be non-negative, finite and have
        a non-zero sum.
    
    Indices are ordered from left to right according to when each was sampled
    (first samples are placed in first column).
    
    If :attr:`input` is a vector, :attr:`out` is a vector of size :attr:`num_samples`.
    
    If :attr:`input` is a matrix with `m` rows, :attr:`out` is an matrix of shape
    :math:`(m \times \text{num\_samples})`.
    
    If replacement is ``True``, samples are drawn with replacement.
    
    If not, they are drawn without replacement, which means that when a
    sample index is drawn for a row, it cannot be drawn again for that row.
    
    .. note::
        When drawn without replacement, :attr:`num_samples` must be lower than
        number of non-zero elements in :attr:`input` (or the min number of non-zero
        elements in each row of :attr:`input` if it is a matrix).
    
    Args:
        input (Tensor): the input tensor containing probabilities
        num_samples (int): number of samples to draw
        replacement (bool, optional): whether to draw with replacement or not

    Computes the matrix-matrix multiplication of a product of Householder matrices with a general matrix.
    
    Multiplies a :math:`m \times n` matrix `C` (given by :attr:`other`) with a matrix `Q`,
    where `Q` is represented using Householder reflectors `(input, tau)`.
    See `Representation of Orthogonal or Unitary Matrices`_ for further details.
    
    If :attr:`left` is `True` then `op(Q)` times `C` is computed, otherwise the result is `C` times `op(Q)`.
    When :attr:`left` is `True`, the implicit matrix `Q` has size :math:`m \times m`.
    It has size :math:`n \times n` otherwise.
    If :attr:`transpose` is `True` then `op` is the conjugate transpose operation, otherwise it's a no-op.
    
    Supports inputs of float, double, cfloat and cdouble dtypes.
    Also supports batched inputs, and, if the input is batched, the output is batched with the same dimensions.

    Takes the power of each element in :attr:`input` with :attr:`exponent` and

    When :attr:`exponent` is a tensor, the shapes of :attr:`input`
    and :attr:`exponent` must be :ref:`broadcastable <broadcasting-semantics>`.

        This is different from :meth:`torch.Tensor.repeat` but similar to ``numpy.repeat``.
    
    Args:
        input (Tensor): the input tensor.
        repeats (Tensor or int): The number of repetitions for each element.
            repeats is broadcasted to fit the shape of the given axis.
        dim (int, optional): The dimension along which to repeat values.
            By default, use the flattened input array, and return a flat output
            array.
    
    Keyword args:
        output_size (int, optional): Total output size for the given axis
            ( e.g. sum of repeats). If given, it will avoid stream synchronization
            needed to calculate output shape of the tensor.
    
    Returns:
        Tensor: Repeated tensor which has the same shape as input, except along the given axis.
    
    Example::
    
        >>> x = torch.tensor([1, 2, 3])
        >>> x.repeat_interleave(2)
        tensor([1, 1, 2, 2, 3, 3])

                [3, 4]])
    
    If the `repeats` is `tensor([n1, n2, n3, ...])`, then the output will be
    `tensor([0, 0, ..., 1, 1, ..., 2, 2, ..., ...])` where `0` appears `n1` times,

    :attr:`ccol_indices` and :attr:`row_indices`. Sparse matrix
    multiplication operations in CSC format are typically faster than that

       given device and in turn determine the device of the constructed
       sparse tensor.
    
    Args:
        ccol_indices (array_like): (B+1)-dimensional array of size
            ``(*batchsize, ncols + 1)``.  The last element of each batch
            is the number of non-zeros. This tensor encodes the index in
            values and row_indices depending on where the given column
            starts. Each successive number in the tensor subtracted by the
            number before it denotes the number of elements in a given
            column.
        row_indices (array_like): Row co-ordinates of each element in
            values. (B+1)-dimensional tensor with the same length as
            values.
        values (array_list): Initial values for the tensor. Can be a list,
            tuple, NumPy ``ndarray``, scalar, and other types that
            represents a (1+K)-dimensional tensor where ``K`` is the number
            of dense dimensions.
        size (list, tuple, :class:`torch.Size`, optional): Size of the
            sparse tensor: ``(*batchsize, nrows, ncols, *densesize)``. If
            not provided, the size will be inferred as the minimum size
            big enough to hold all non-zero elements.
    
    Keyword args:
        dtype (:class:`torch.dtype`, optional): the desired data type of
            returned tensor.  Default: if None, infers data type from
            :attr:`values`.

            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``.
        check_invariants (bool, optional): If sparse tensor invariants are checked.

    std_mean(input, dim=None, *, correction=1, keepdim=False, out=None) -> (Tensor, Tensor)
    
    Calculates the standard deviation and mean over the dimensions specified by
    :attr:`dim`. :attr:`dim` can be a single dimension, list of dimensions, or
    ``None`` to reduce over all dimensions.
    
    The standard deviation (:math:`\sigma`) is calculated as
    
    .. math:: \sigma = \sqrt{\frac{1}{\max(0,~N - \delta N)}\sum_{i=0}^{N-1}(x_i-\bar{x})^2}
    
    where :math:`x` is the sample set of elements, :math:`\bar{x}` is the
    sample mean, :math:`N` is the number of samples and :math:`\delta N` is
    the :attr:`correction`.
    
    
    
    
    If :attr:`keepdim` is ``True``, the output tensor is of the same size
    as :attr:`input` except in the dimension(s) :attr:`dim` where it is of size 1.
    Otherwise, :attr:`dim` is squeezed (see :func:`torch.squeeze`), resulting in the
    output tensor having 1 (or ``len(dim)``) fewer dimension(s).
    
    
    Args:
        input (Tensor): the input tensor.
        
        dim (int or tuple of ints, optional): the dimension or dimensions to reduce.
            If ``None``, all dimensions are reduced.
    
    
    Keyword args:
        correction (int): difference between the sample size and sample degrees of freedom.
            Defaults to `Bessel's correction`_, ``correction=1``.

                with ``True`` corresponding to ``correction=1`` and ``False`` being

        keepdim (bool): whether the output tensor has :attr:`dim` retained or not.
        out (Tensor, optional): the output tensor.

    r"""
    svd(input, some=True, compute_uv=True, *, out=None) -> (Tensor, Tensor, Tensor)
    
    Computes the singular value decomposition of either a matrix or batch of
    matrices :attr:`input`. The singular value decomposition is represented as a
    namedtuple `(U, S, V)`, such that :attr:`input` :math:`= U \text{diag}(S) V^{\text{H}}`.
    where :math:`V^{\text{H}}` is the transpose of `V` for real inputs,
    and the conjugate transpose of `V` for complex inputs.
    If :attr:`input` is a batch of matrices, then `U`, `S`, and `V` are also
    batched with the same batch dimensions as :attr:`input`.
    
    If :attr:`some` is `True` (default), the method returns the reduced singular
    value decomposition. In this case, if the last two dimensions of :attr:`input` are
    `m` and `n`, then the returned `U` and `V` matrices will contain only
    `min(n, m)` orthonormal columns.
    
    If :attr:`compute_uv` is `False`, the returned `U` and `V` will be
    zero-filled matrices of shape `(m, m)` and `(n, n)`
    respectively, and the same device as :attr:`input`. The argument :attr:`some`
    has no effect when :attr:`compute_uv` is `False`.
    
    Supports :attr:`input` of float, double, cfloat and cdouble data types.
    The dtypes of `U` and `V` are the same as :attr:`input`'s. `S` will
    always be real-valued, even if :attr:`input` is complex.
    
    .. warning::
    
        :func:`torch.svd` is deprecated in favor of :func:`torch.linalg.svd`
        and will be removed in a future PyTorch release.
    
        ``U, S, V = torch.svd(A, some=some, compute_uv=True)`` (default) should be replaced with
    
        .. code:: python
    
            U, S, Vh = torch.linalg.svd(A, full_matrices=not some)

        .. code:: python
    
            S = torch.linalg.svdvals(A)
    
    .. note:: Differences with :func:`torch.linalg.svd`:
    
                 * :attr:`some` is the opposite of
                   :func:`torch.linalg.svd`'s :attr:`full_matrices`. Note that
                   default value for both is `True`, so the default behavior is
                   effectively the opposite.
                 * :func:`torch.svd` returns `V`, whereas :func:`torch.linalg.svd` returns
                   `Vh`, that is, :math:`V^{\text{H}}`.
                 * If :attr:`compute_uv` is `False`, :func:`torch.svd` returns zero-filled
                   tensors for `U` and `Vh`, whereas :func:`torch.linalg.svd` returns
                   empty tensors.
    
    .. note:: The singular values are returned in descending order. If :attr:`input` is a batch of matrices,
              then the singular values of each matrix in the batch are returned in descending order.
    
    .. note:: The `S` tensor can only be used to compute gradients if :attr:`compute_uv` is `True`.
    
    .. note:: When :attr:`some` is `False`, the gradients on `U[..., :, min(m, n):]`
              and `V[..., :, min(m, n):]` will be ignored in the backward pass, as those vectors
              can be arbitrary bases of the corresponding subspaces.
    
    .. note:: The implementation of :func:`torch.linalg.svd` on CPU uses LAPACK's routine `?gesdd`
              (a divide-and-conquer algorithm) instead of `?gesvd` for speed. Analogously,
              on GPU, it uses cuSOLVER's routines `gesvdj` and `gesvdjBatched` on CUDA 10.1.243
              and later, and MAGMA's routine `gesdd` on earlier versions of CUDA.
    
    .. note:: The returned `U` will not be contiguous. The matrix (or batch of matrices) will
              be represented as a column-major matrix (i.e. Fortran-contiguous).
    
    .. warning:: The gradients with respect to `U` and `V` will only be finite when the input does not
                 have zero nor repeated singular values.
    
    .. warning:: If the distance between any two singular values is close to zero, the gradients with respect to
                 `U` and `V` will be numerically unstable, as they depends on
                 :math:`\frac{1}{\min_{i \neq j} \sigma_i^2 - \sigma_j^2}`. The same happens when the matrix
                 has small singular values, as these gradients also depend on `S^{-1}`.
    
    .. warning:: For complex-valued :attr:`input` the singular value decomposition is not unique,
                 as `U` and `V` may be multiplied by an arbitrary phase factor :math:`e^{i \phi}` on every column.
                 The same happens when :attr:`input` has repeated singular values, where one may multiply
                 the columns of the spanning subspace in `U` and `V` by a rotation matrix
                 and `the resulting vectors will span the same subspace`_.
                 Different platforms, like NumPy, or inputs on different device types,
                 may produce different `U` and `V` tensors.
    
    Args:
        input (Tensor): the input tensor of size `(*, m, n)` where `*` is zero or more

        some (bool, optional): controls whether to compute the reduced or full decomposition, and
                               consequently, the shape of returned `U` and `V`. Default: `True`.

    Computes the `trapezoidal rule <https://en.wikipedia.org/wiki/Trapezoidal_rule>`_ along
    :attr:`dim`. By default the spacing between elements is assumed to be 1, but
    :attr:`dx` can be used to specify a different constant spacing, and :attr:`x` can be
    used to specify arbitrary spacing along :attr:`dim`.
    
    
    Assuming :attr:`y` is a one-dimensional tensor with elements :math:`{y_0, y_1, ..., y_n}`,
    the default computation is
    
    .. math::

    When :attr:`x` and :attr:`y` have the same size, the computation is as described above and no broadcasting is needed.
    The broadcasting behavior of this function is as follows when their sizes are different. For both :attr:`x`
    and :attr:`y`, the function computes the difference between consecutive elements along
    dimension :attr:`dim`. This effectively creates two tensors, `x_diff` and `y_diff`, that have
    the same shape as the original tensors except their lengths along the dimension :attr:`dim` is reduced by 1.
    After that, those two tensors are broadcast together to compute final output as part of the trapezoidal rule.
    See the examples below for details.
    
    .. note::
        The trapezoidal rule is a technique for approximating the definite integral of a function
        by averaging its left and right Riemann sums. The approximation becomes more accurate as
        the resolution of the partition increases.
    
    Arguments:
        y (Tensor): Values to use when computing the trapezoidal rule.
        x (Tensor): If specified, defines spacing between values as specified above.
    
    Keyword arguments:
        dx (float): constant spacing between values. If neither :attr:`x` or :attr:`dx`
            are specified then this defaults to 1. Effectively multiplies the result by its value.
        dim (int): The dimension along which to compute the trapezoidal rule.

    Indices are ordered based on rows and then columns.
    
    The lower triangular part of the matrix is defined as the elements on and
    below the diagonal.
    
    The argument :attr:`offset` controls which diagonal to consider. If
    :attr:`offset` = 0, all elements on and below the main diagonal are
    retained. A positive value includes just as many diagonals above the main
    diagonal, and similarly a negative value excludes just as many diagonals below
    the main diagonal. The main diagonal are the set of indices
    :math:`\lbrace (i, i) \rbrace` for :math:`i \in [0, \min\{d_{1}, d_{2}\} - 1]`
    where :math:`d_{1}, d_{2}` are the dimensions of the matrix.
    
    .. note::
        When running on CUDA, ``row * col`` must be less than :math:`2^{59}` to
        prevent overflow during calculation.

        dtype (:class:`torch.dtype`, optional): the desired data type of returned tensor.
            Default: if ``None``, ``torch.long``.
        device (:class:`torch.device`, optional): the desired device of returned tensor.
            Default: if ``None``, uses the current device for the default tensor type
            (see :func:`torch.set_default_device`). :attr:`device` will be the CPU
            for CPU tensor types and the current CUDA device for CUDA tensor types.

    vander(x, N=None, increasing=False) -> Tensor
    
    Generates a Vandermonde matrix.
    
    The columns of the output matrix are elementwise powers of the input vector :math:`x^{(N-1)}, x^{(N-2)}, ..., x^0`.
    If increasing is True, the order of the columns is reversed :math:`x^0, x^1, ..., x^{(N-1)}`. Such a
    matrix with a geometric progression in each row is named for Alexandre-Theophile Vandermonde.
    
    Arguments:
        x (Tensor): 1-D input tensor.
        N (int, optional): Number of columns in the output. If N is not specified,
            a square array is returned :math:`(N = len(x))`.
        increasing (bool, optional): Order of the powers of the columns. If True,
            the powers increase from left to right, if False (the default) they are reversed.
    
    Returns:
        Tensor: Vandermonde matrix. If increasing is False, the first column is :math:`x^{(N-1)}`,
        the second :math:`x^{(N-2)}` and so forth. If increasing is True, the columns

    it must evenly divide the split dimension or a runtime error will be thrown.
    
    This function is based on NumPy's :func:`numpy.vsplit`.

        input (Tensor): tensor to split.
        indices_or_sections (int or list or tuple of ints): See argument in :func:`torch.tensor_split`.
