在输入上执行分数平均池化。
分数平均池化类似于常规平均池化。在常规平均池中,可以通过获取集合中较小的 `N x N` 子部分通常为2x2的平均值来缩小输入集的大小
并尝试将集合减少N的因子其中N是整数。分数平均池化意味着整体缩减比N不必是整数。在每个池化区域中执行均值运算。
分数平均池化类似于常规平均池化。在常规平均池化中,通过取集合较小的 `N x N` 子部分的平均值通常为2x2来缩小输入集的大小目标是将集合缩小 `N` 倍,其中 `N` 为整数。
但分数平均池化具有额外的灵活性,允许总缩小比率 `N` 为非整数值。

Inputs:
- **x** (Tensor) - Rank r + 1, where r >= 1.
- **diagonal** (Tensor) - A Tensor. Have the same dtype as x. Rank r when k is an integer or k[0] == k[1].
Otherwise, it has rank r + 1.
- **k** (Tensor) - A Tensor of type int32. Diagonal offset(s). Positive value means superdiagonal, 0 refers to
the main diagonal, and negative value means subdiagonals. k can be a single integer (for a single diagonal) or
a pair of integers specifying the low and high ends of a matrix band. `k[0]` must not be larger than `k[1]` .
The value of `k` has restructions, meaning value of k must be in (-x.shape[-2], x.shape[-1]).
Input k must be const Tensor when taking Graph mode.
- **x** (Tensor) - A n-D Tensor, where :math:`n >= 2`.
- **diagonal** (Tensor) - A Tensor with the same dtype as `x`. Its rank depends on `k`.
If `k` is an integer or :math:`k[0] == k[1]`, its dimension is :math:`n-1`.
Otherwise, it has dimension :math:`n`.
- **k** (Tensor) - Tensor type int32, used for diagonal offset(s).
`k` can either be a single integer, which represents a single diagonal,
or a pair of integers that specify the low and high ends of a matrix band.
In this case(这里是指什么情况下), `k[0]` should not be greater than `k[1]`.
The value of `k` has restructions, which means that value of `k` must be in range (-x.shape[-2], x.shape[-1]).
Input `k` must be const Tensor when taking Graph mode.
- `k > 0` refers to a superdiagonal.
- `k = 0` refers to the main diagonal.
- `k < 0` refers to subdiagonals.
Outputs:
Tensor. The same type as x.
Let x has r+1 dimensions :math:`[I, J, ..., L, M, N]` .
The output is a tensor of rank r+1 with dimensions :math:`[I, J, ..., L, M, N]` , the same as input x.
