*@brief Computes the "logical or" of elements across dimensions of a tensor.
* Reduces "x" along the dimensions given in "axes".
* Unless "keep_dims" is true, the rank of the tensor is reduced by 1 for each
* entry in "axes". If "keep_dims" is true, the reduced dimensions
* are retained with length 1.
*
* If "axis" is None, all dimensions are reduced, and a
* tensor with a single element is returned.
*
*@attention Constraints:
*  Only support bool
*
*@par Inputs:
* x: The boolean tensor to reduce.
*
*@par Attributes:
*@li axes: The dimensions to reduce. Must be in the range "[-rank(x), rank(x))".
*@li keep_dims: If true, retains reduced dimensions with length 1.
*
*@par Outputs:
* y: The reduced tensor
*
*@par Third-party framework compatibility
*Compatible with the TensorFlow operator reduce_any.

/**
*@brief Compute reduction on dimensions specified by "axis". 
*Four reduction operations are provided:
*SUM     Computes the sum of elements across specified dimensions of a tensor.
*ASUM    Computes the sum of absolute values of elements across specified dimensions of a tensor.
*SUMSQ   Computes the sum of squares of elements across specified dimensions of a tensor.
*SUMSQ   Computes the mean values of elements across specified dimensions of a tensor.

*@par Inputs: 
*x: A Tensor of type float16 or float32

*@par Attributes:
*@li operation: An optional int32 from 1(SUM), 2(ASUM), 3(SUMSQ), and 4(MEAN), 
*specifying the reduction algorithm. Defaults to 1.
*@li axis: An optional int32, specifying the first axis to reduce. Defaults to "0". 
*The value range is [-N, N-1], where N is the input tensor rank.
*@li coeff: An optional float32, specifying the scale coefficient. Defaults to "1.0".

*@par Outputs: 
*y: A Tensor. Has the same type as "x".

*@attention Constraints: The Reduction operator supports type float16 only on the device chip.
*@par Third-party framework compatibility
* Compatible with the Caffe operator Reduction.
