self.updown = up or down if up: self.h_upd = Upsample(channels, False, dims) self.x_upd = Upsample(channels, False, dims) elif down: self.h_upd = Downsample(channels, False, dims) self.x_upd = Downsample(channels, False, dims) else: self.h_upd = self.x_upd = nn.Identity()中x_upd是什么意思
x_upd是一个变量,它在代码中被赋值为Upsample或Downsample或nn.Identity()。具体来说,如果up为True,则x_upd被赋值为Upsample;如果down为True,则x_upd被赋值为Downsample;否则,x_upd被赋值为nn.Identity()。在代码中,x_upd被用于更新隐藏状态。
详细解释一下这段代码self.updown = up or down if up: self.h_upd = Upsample(channels, False, dims) self.x_upd = Upsample(channels, False, dims) elif down: self.h_upd = Downsample(channels, False, dims) self.x_upd = Downsample(channels, False, dims) else: self.h_upd = self.x_upd = nn.Identity()
这段代码是一个类中的初始化函数,其中self.updown是一个布尔值,表示是否进行上采样或下采样。如果up为真,则进行上采样,使用Upsample函数进行操作;如果down为真,则进行下采样,使用Downsample函数进行操作;如果既不是上采样也不是下采样,则使用nn.Identity()函数进行操作。其中,channels表示通道数,dims表示维度。
