r"""
The torch package contains data structures for multi-dimensional
tensors and defines mathematical operations over these tensors.
Additionally, it provides many utilities for efficient serialization of
Tensors and arbitrary types, and other useful utilities.

It has a CUDA counterpart, that enables you to run your tensor computations
on an NVIDIA GPU with compute capability >= 3.0.

def set_default_dtype(d):

    Sets the default floating point dtype to :attr:`d`. Supports torch.float32
    and torch.float64 as inputs. Other dtypes may be accepted without complaint
    but are not supported and are unlikely to work as expected.

    When PyTorch is initialized its default floating point dtype is torch.float32,
    and the intent of set_default_dtype(torch.float64) is to facilitate NumPy-like
    type inference. The default floating point dtype is used to:

    1. Implicitly determine the default complex dtype. When the default floating point
       type is float32 the default complex dtype is complex64, and when the default
       floating point type is float64 the default complex type is complex128.
    2. Infer the dtype for tensors constructed using Python floats or complex Python
       numbers. See examples below.
    3. Determine the result of type promotion between bool and integer tensors and
       Python floats and complex Python numbers.

    Args:
        d (:class:`torch.dtype`): the floating point dtype to make the default.
                                  Either torch.float32 or torch.float64.

    Example:
        >>> # xdoctest: +SKIP("Other tests may have changed the default type. Can we reset it?")
        >>> # initial default for floating point is torch.float32
        >>> # Python floats are interpreted as float32

    A handful of CUDA operations are nondeterministic if the CUDA version is
    10.2 or greater, unless the environment variable ``CUBLAS_WORKSPACE_CONFIG=:4096:8``
    or ``CUBLAS_WORKSPACE_CONFIG=:16:8`` is set. See the CUDA documentation for more
    details: `<https://docs.nvidia.com/cuda/cublas/index.html#cublasApi_reproducibility>`_
    If one of these environment variable configurations is not set, a :class:`RuntimeError`
    will be raised from these operations when called with CUDA tensors:

        * :func:`torch.mm`
        * :func:`torch.mv`
        * :func:`torch.bmm`

    Note that deterministic operations tend to have worse performance than
    nondeterministic operations.

    .. note::

        This flag does not detect or prevent nondeterministic behavior caused
        by calling an inplace operation on a tensor with an internal memory
        overlap or by giving such a tensor as the :attr:`out` argument for an
        operation. In these cases, multiple writes of different data may target
        a single memory location, and the order of writes is not guaranteed.

    Args:
        mode (:class:`bool`): If True, makes potentially nondeterministic
            operations switch to a deterministic algorithm or throw a runtime
            error. If False, allows nondeterministic operations.

    Keyword args:
        warn_only (:class:`bool`, optional): If True, operations that do not
            have a deterministic implementation will throw a warning instead of
            an error. Default: ``False``

        * "high", float32 matrix multiplications use the TensorFloat32 or bfloat16_3x
