argmax_cuda“未针对'Bool实现

Question

我在google collab中遇到此错误。我尝试了其他数据类型，例如布尔张量，但没有用，请帮助

代码

 def _mask(prev_generated_seq):
        prev_mask = torch.eq(prev_generated_seq, 1)
        lengths = torch.argmax(prev_mask,dim=1)
        #test = torch.max(prev_mask,dim=1)
        #lengths = torch.FloatTensor(test)
        max_len = prev_generated_seq.size(1)
        mask = []
        for i in range(prev_generated_seq.size(0)):
            if lengths[i] == 0:
                mask_line = [0] * max_len
            else:
                mask_line = [0] * lengths[i].item()
                mask_line.extend([1] * (max_len - lengths[i].item()))
            mask.append(mask_line)
        mask = torch.ByteTensor(mask)
        if args.cuda:
            mask = mask.cuda()
        return prev_generated_seq.data.masked_fill_(mask, 0)
