pytorch conv2d值无法转换为uint8_t类型而不溢出

我正在传递一个torch.Tensor with a dtype of torch.uint8 to an nn.Conv2d模块，它给出了错误

运行时错误：值无法转换为 uint8_t 类型，无需 溢出：-0.0344873

我的 conv2d 定义为self.conv1 = nn.Conv2d(3, 6, 5)。错误出现在我的forward当我将张量传递给模块时的方法self.conv1(x)。张量的形状为 (4, 3, 480, 640)。我不知道如何解决这个问题。这是堆栈跟踪

将张量转换为浮点数似乎可以修复它self.conv1(x.float())
