1. RuntimeError: multi-target not supported错误的含义 这个错误表示在PyTorch中,某个操作不支持多个目标标签(multi-target)。在使用分类交叉熵损失函数(CrossEntropyLoss)时,每个样本只能对应一个目标标签,而该错误通常发生在尝试为每个样本指定多个标签时。 2. 该错误通常发生在什么情况下 这个错误通常发生在以下情...
我们使用了nn.CrossEntropyLoss()作为损失函数,该函数要求目标值为一维标签。通过使用.squeeze()方法将多维的目标值压缩为一维向量,我们可以避免 "1D target tensor expected, multi-target not supported" 错误的发生。 squeeze()方法是PyTorch张量(Tensor)类的一个方法,用于减少张量维度中的尺寸为1的维度。具体而言,...
解决pytorch下出现multi-targetnotsupportedat的⼀种可 能原因 在使⽤交叉熵损失函数的时候，target的形状应该是和label的形状⼀致或者是只有batchsize这⼀个维度的。如果target是这样的【batchszie，1】就会出现上述的错误。改⼀下试试，⽤squeeze（）函数降低纬度，如果不知道squeeze怎么⽤的，可以参考这篇...
BUG 使用Cross_entropy损失函数时出现 RuntimeError: multi-target not supported at … 可能存在的问题 1)其标签必须为0~n-1,而且必须为1维的,如果设置标签为[nx1]的,则也会出现以上错误。 2)标签y打印: tensor([[1, 0], [1, 0], [1, 0], [1, 0], [1, 0], [1, 0], [1, ...

not accessible. Recent research addresses this by adapting single source21or multiple sources as in DECISION method22to the target domain without access to the source data, meanwhile assuming that sufficient target data is accessible. But in practical scenarios like facial emotion recognition in ...
