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...
set.push(handler)if('addEventListener'inelement)element.addEventListener(realEvent(handler.e),handler.proxy,eventCapture(handler,capture))})} 在这里先跳过id以及handler部分(handler.e的值即为事件的type属性),该函数主要作用就是将事件添加进元素的事件队列里。 首先是对events进行分割成多个事件,并通过each函数...
