pytorch masked_fill方法理解 mask必须是一个 ByteTensor 而且shape的最大维度必须和 a一样 并且元素只能是 0或者1 , 是将mask中为1的 元素所在的索引,在a中相同的的索引处替换为 value importtorcha=torch.tensor([[[5,5,5,5],[6,6,6,6],[7,7,7,7]],[[1,1,1,1],[2,2,2,2],[3,3,3,...
一、函数 1.1 masked_fill pytorch masked_fill 输入数据的维度为【batch_size,seq_len,embedding_size】mask和输入数据是相同的数据维度,但mask的整型数据,并且要不是0,要不是1,masked_fill会对数据数据对应的mask,如果是1则替换成设定值,0则不变 # -*-coding:utf-8-*-importtorchorigin=torch.nn.init.xavi...
tensor([0.0000, 0.0000, 0.2689, 0.7311])容易报错:Expected object of scalar type Byte but got scalar type Long for argument #2 'mask'原因,mask = torch.LongTensor()解决⽅法:mask = torch.ByteTensor()在mask值为1的位置处⽤value填充。mask的元素个数需和本tensor相同,但尺⼨可以不同...

masked_fill_ returns an incorrect result on MPS where as masked_fill does not. See discussion here pytorch/pytorch#131285
