torch.clamp(input,min,max)
- 对输入的 input 张量中每个值做截断操作
input(Tensor)
,输入张量;min(Number)
,截断范围最小值;max(Number)
,截断范围最大值;
例子如下
>>> a = torch.randn(4) >>> a tensor([-1.7120, 0.1734, -0.0478, -0.0922]) >>> torch.clamp(a, min=-0.5, max=0.5) tensor([-0.5000, 0.1734, -0.0478, -0.0922])
torch.div(input,other)
- 将
input
张量中值除以other
张量中对应的元素值,other
可为张量也可为 标量
参数解析
input(Tensor)
,输入张量,作为被除数;other(Tensor or Number)
,作除数的张量或标量;
代码示例
>>> a = torch.randn(5) >>> a tensor([ 0.3810, 1.2774, -0.2972, -0.3719, 0.4637]) >>> torch.div(a, 0.5) tensor([ 0.7620, 2.5548, -0.5944, -0.7439, 0.9275]) >>> a = torch.randn(4, 4) >>> a tensor([[-0.3711, -1.9353, -0.4605, -0.2917], [ 0.1815, -1.0111, 0.9805, -1.5923], [ 0.1062, 1.4581, 0.7759, -1.2344], [-0.1830, -0.0313, 1.1908, -1.4757]]) >>> b = torch.randn(4) >>> b tensor([ 0.8032, 0.2930, -0.8113, -0.2308]) >>> torch.div(a, b) tensor([[-0.4620, -6.6051, 0.5676, 1.2637], [ 0.2260, -3.4507, -1.2086, 6.8988], [ 0.1322, 4.9764, -0.9564, 5.3480], [-0.2278, -0.1068, -1.4678, 6.3936]])
