FunctionDescriptionDetailabsComputes the absolute value of each element in input.返回元素的绝对值absoluteAlias for torch.abs()torch.abs 的别名ceilReturns a new tensor with the ceil of the elements of input, the smallest integer greater than or equal to each element.对元素向上取整roundReturns a new tensor with each of the elements of input rounded to the closest integer.对元素四舍五入floorReturns a new tensor with the floor of the elements of input, the largest integer less than or equal to each element.对元素向下取整

torch.abs
原型
torch.abs(input, *, out=None) → Tensor
说明
对张量里的每一个元素计算绝对值 o u t i = ∣ i n p u t i ∣ out_i = | input_i | outi=∣inputi∣ 例子 >>> torch.abs(torch.tensor([-1, -2, 3])) tensor([ 1, 2, 3]) torch.ceil 原型 torch.ceil(input, *, out=None) → Tensor 说明向上取整 o u t i = ⌈ i n p u t i ⌉ out_i = \left \lceil input_i \right \rceil outi=⌈inputi⌉ 例子 >>> a = torch.randn(4) >>> a tensor([-0.6341, -1.4208, -1.0900, 0.5826]) >>> torch.ceil(a) tensor([-0., -1., -1., 1.]) torch.round 原型 torch.round(input, *, out=None) → Tensor 说明四舍五入 例子 >>> a = torch.randn(4) >>> a tensor([ 0.9920, 0.6077, 0.9734, -1.0362]) >>> torch.round(a) tensor([ 1., 1., 1., -1.]) torch.floor 原型 torch.floor(input, *, out=None) → Tensor 说明向下取整 o u t i = ⌊ i n p u t i ⌋ out_i = \left \lfloor input_i \right \rfloor outi=⌊inputi⌋ 例子 >>> a = torch.randn(4) >>> a tensor([-0.8166, 1.5308, -0.2530, -0.2091]) >>> torch.floor(a) tensor([-1., 1., -1., -1.]) |
