class LinearReLU(nnq.Linear):
    r"""
    A LinearReLU module fused from Linear and ReLU modules

    We adopt the same interface as :class:`torch.nn.quantized.Linear`.

    Attributes:
        Same as torch.nn.quantized.Linear

    Examples::

        >>> m = nn.intrinsic.LinearReLU(20, 30)
        >>> input = torch.randn(128, 20)
        >>> output = m(input)
        >>> print(output.size())
        torch.Size([128, 30])
