(1)r=S(q−Z) (看不懂的可以再参考一下我之前的文章) 这里面 r 是实数域中的数值 (一般是 float),q 则是量化后的整型数值 (常用的是 int8)。 EltwiseAdd 就是对两个 tensor 的数值逐个相加。假设两个 tensor 中的数值分别是 r1、r2,相加得到的和用 r3 表示,那全精度下的EltwiseAdd 可以表示为:...
在上篇文章Pytorch internals - 以add算子为例理解elementwise_kernel和TensorIterator的调用流程中,我们了解到了add算子经过其内部的派发器(Dispatcher)进行派发后,最终会调用三个对应的kenel,我们来看看他们的函数声明: at::Tensorwrapper_CUDA_add_Tensor(constat::Tensor&self,constat::Tensor&other,constat::Scalar...

In PyTorch,Tensorsare multidimensional arrays that are utilized to store and represent data. Tensors have many attributes and methods that permit users to perform various operations on them, such as reshaping, indexing, slicing, arithmetic, and many more. Moreover, PyTorch also enables users to ...

这段代码首先将进程 0 和 1 组成进程组,然后将各自进程中 tensor(1) 相加。由于我们需要组中所有张量的总和,因此我们将 dist.reduce_op.SUM 用作化简运算符。一般来说,任何可交换的数学运算都可以用作运算符。PyTorch 开箱即用,带有 4 个这样的运算符,它们...
