这个错误提示是由于在进行tensor的操作时,两个tensor在第3个维度上的大小不匹配所导致的。可能是由于你在进行某个操作时,没有考虑到两个tensor的形状是否匹配。
你需要检查一下你的代码,看看在哪里出现了这个错误。你可以通过打印tensor的形状来帮助你找到问题所在。如果你仍然无法解决问题,可以提供更多的信息,我会尽力帮助你解决问题。

The size of tensor a (512) must match the size of tensor b (256) at non-singleton dimension 3
这是一个关于张量操作的问题。在深度学习或Python的库如PyTorch或TensorFlow中,当我们尝试相加、矩阵乘法等操作两个张量(tensor)时,它们必须在非单元素维度上具有相同的大小。在这个例子中,tensor a 的第三个非单元素维度(dimension 3)大小是 512,而 tensor b 的第三个非单元素维度是 256。这意味着这两个张量在维度3上的元素数量不匹配,如果不做调整直接运算,会引发错误。
通常,在进行张量运算之前,我们需要对它们进行适当的reshape(重塑形状)或者transposing(转置)操作,以便在指定维度上匹配尺寸。如果不需要改变内容,也可以通过broadcasting(广播机制)来解决,但这只适用于特定规则,比如数值可以沿着一个轴进行扩展。
The size of tensor a (32) must match the size of tensor b (512) at non-singleton dimension 1
The error message "The size of tensor a (32) must match the size of tensor b (512) at non-singleton dimension 1" indicates that there is a size mismatch between two tensors in dimension 1. In order to perform operations between tensors, their sizes must match along all dimensions except for the singleton dimensions.
To resolve this error, you can check the shape of tensor a and tensor b along dimension 1 and ensure they have the same size. If they don't have the same size, you may need to reshape or resize one or both tensors to match their sizes.
