错误提示：

view size is not compatible with input tensor's size and stride (at least one dimension spans across two contiguous subspaces). Use .reshape(...) instead.

错误代码：

prec1 = accuracy(-1 * dist_xt_ct.data, target_targets, topk=(1,))[0].item()

正确代码：

prec1 = accuracy(-1 * dist_xt_ct.data, target_targets, topk=(1,)).item()

将[0]去掉即可！
