+QLinearGlobalAveragePool consumes an input tensor X and applies
+Average pooling across the values in the same channel. This is
+equivalent to AveragePool with kernel size equal to the spatial
+dimension of input tensor. Input is of type uint8_t or int8_t.
+
+Version
+This version of the operator has been available since version 1 of the 'com.microsoft' operator set.
+
+Attributes
+channels_last : int
+
+Inputs
+X : T
+
+Input data tensor from the previous operator; According to channels_last, dimensions for image case
+are (N x C x H x W), or (N x H x W x C) where N is the batch size, C is the number of channels, and
+H and W are the height and the width of the data. For non image case, the dimensions are in the form
+of (N x C x D1 x D2 ... Dn), or (N x D1 X D2 ... Dn x C) where N is the batch size.
+
+x_scale : tensor(float)
+Scale of quantized input 'X'. It must be a scalar.
+
+x_zero_point : T
+Zero point tensor for input 'X'. It must be a scalar.
+
+y_scale : tensor(float)
+Scale of quantized output 'Y'. It must be a scalar.
+
+y_zero_point : T
+Zero point tensor for output 'Y'. It must be a scalar.
+
+Outputs
+Y : T
+Output data tensor from pooling across the input tensor. The output tensor has the same rank as the
+input. with the N and C value keep it value, while the other dimensions are all 1. Type Constraints
+T : tensor(uint8), tensor(int8)
+Constrain input and output types to signed/unsigned int8 tensors.

+Matrix product that behaves like numpy.matmul:
+
+https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.matmul.html. It consumes two
+quantized input tensors, their scales and zero points, scale and zero point of output, and computes
+the quantized output. The quantization formula is y = saturate((x / y_scale) + y_zero_point). For (x
+/ y_scale), it is rounding to nearest ties to even. Refer to https://en.wikipedia.org/wiki/Rounding
+for details. Scale and zero point must have same shape. They must be either scalar (per tensor) or
+N-D tensor (per row for ‘a’ and per column for ‘b’). Scalar refers to per tensor quantization
+whereas N-D refers to per row or per column quantization. If the input is 2D of shape [M, K] then
+zero point and scale tensor may be an M element vector [v_1, v_2, …, v_M] for per row quantization
+and K element vector of shape [v_1, v_2, …, v_K] for per column quantization. If the input is N-D
+tensor with shape [D1, D2, M, K] then zero point and scale tensor may have shape [D1, D2, M, 1] for
+per row quantization and shape [D1, D2, 1, K] for per column quantization. Production must never
+overflow, and accumulation may overflow if and only if in 32 bits.
