解决pytorch多线程共享全局变量问题:Cannot re-initialize CUDA in forked subprocess. To use CUDA with multiprocessing 原因:在Python3中使用spawn或forkseverver启动方法才支持在进程之间共享CUDA张量。而我是用的multiprocessing是使用fork创建子进程,不被 CUDA 运行时所支持...

首先，我们需要明确大模型训练与推理的基本需求。大模型通常意味着更高的计算需求和数据存储需求。因此，...
Compute Platform:表示安装GPU版还是CPU版本,只支持nvidia的显卡,如果本机没有可用显卡,就安装CPU版本,否则选择CUDA安装。注意如果要安装GPU版本,还需要安装对应的GPU驱动,包括对应的CUDA和cuDNN。参考:https://zhuanlan.zhihu.com/p/106133822 Tensor 基础操作 ...
