Expected all tensors to be on the same device, but found at least two devices, cuda:1 and cuda:0!

这个错误意味着你的代码中有至少两个不同的设备，而期望所有的张量都在同一个设备上。解决这个问题有几种方法。首先，你可以确保你的模型已经移动到与数据相同的设备上，可以使用`model.to(device)`将模型移动到指定的设备上。此外，你还需要确保输入数据和模型参数都在相同的设备上，可以使用类似的操作`data.to(device)`将数据移动到指定的设备上。另外，在代码的最上方，你可以添加一行代码`device = torch.device('cuda:0' if torch.cuda.is_available() else 'cpu')`来指定使用的设备。这样可以确保设备的一致性，从而解决这个错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
