我们可以认为张量由数据本身和一些描述张量各方面的元数据组成,例如张量的形状或张量所在的设备(如 CPU 内存、GPU 内存...)。 还有一种不太流行的元数据,你可能从未听说过,叫做 stride。这个概念对于理解张量数据重排的内部结构非常重要,因此我们需要对它多做一些讨论。想象一个形状为 [4, 8] 的二维张量,如下图...
ACK基于Scheduling Framework机制,实现GPU拓扑感知调度,即在节点的GPU组合中选择具有最优训练速度的组合。本文介绍如何使用GPU拓扑感知调度来提升PyTorch分布式训练的训练速度。 前提条件 已创建ACK Pro集群,且集群的实例规格类型选择为GPU云服务器。更多信息,请参...

I have the same problem: If you upgrade to Pytorch 1.6 then the GPU doesn't work in Kaggle Notebooks. This is especially problematic if you want to use fastai2, since pip install fastai2 upgrades Pytorch 1.5 to 1.6. Anybody was able to use fastai2 in the last few days with GPU? Om...
