Numworkers pytorch

Web23 nov. 2024 · What Is Number Of Workers In Pytorch? The num_workers function tells the data instance loader how many subprocesses to use for data loading. If the num_worker value is zero (default), the GPU must weigh CPU to load data. As a result, greater num_workers results in a faster CPU load time and less GPU waiting time. The Benefits … Web10、pytorch分布式训练参数调整结合自己的经验做一个总结!! ... 本人测试过,将num_workers设置的非常大,例如,24,32,等,其效率反而降低,因为模型需要将数据平均分配到几个子线程去进行预处理,分发等数据操作,设高了反而影响效率。
