torch.add¶
- torch.add(input, other, *, alpha=1, out=None) Tensor ¶
将
other
(乘以alpha
)加到input
上。- 参数
- 关键字参数
alpha (Number) –
other
的乘数。out (Tensor, 可选) – 输出张量。
示例
>>> a = torch.randn(4) >>> a tensor([ 0.0202, 1.0985, 1.3506, -0.6056]) >>> torch.add(a, 20) tensor([ 20.0202, 21.0985, 21.3506, 19.3944]) >>> b = torch.randn(4) >>> b tensor([-0.9732, -0.3497, 0.6245, 0.4022]) >>> c = torch.randn(4, 1) >>> c tensor([[ 0.3743], [-1.7724], [-0.5811], [-0.8017]]) >>> torch.add(b, c, alpha=10) tensor([[ 2.7695, 3.3930, 4.3672, 4.1450], [-18.6971, -18.0736, -17.0994, -17.3216], [ -6.7845, -6.1610, -5.1868, -5.4090], [ -8.9902, -8.3667, -7.3925, -7.6147]])
