HIFIGAN 1D to 2D疑问

[MarsMeng1994]

请问下，为什么hifigan的MPD的1D->2D是这样实现的呀？ `def forward(self, x): fmap = []

    # 1d to 2d
    b, c, t = x.shape
    if t % self.period != 0:  # pad first
        n_pad = self.period - (t % self.period)
        x = F.pad(x, (0, n_pad), "reflect")
        t = t + n_pad
    x = x.view(b, c, t // self.period, self.period)

` 从图上来看，比如【1,2,3,4,5,6】应该变成【【1,3,5】，【2,4,6】】嘛？

把那个图倒过来，竖着看，不就是 [[1, 2] [3, 4], [5, 6]]
