踩坑日志2:dataloader的num_workers问题 当我想用dataloader多开子进程加快图片加载速度时,发现报有关进程的错误: RuntimeError: An attempt has been made to start a new process before the current process has finished its bootstrapping phase. This probably means that you arenotusing fork to start your...
在任务管理器的“性能”选项卡中选择“CPU”,查看你的CPU核心和逻辑处理器数量。 确保num_workers不要超过逻辑处理器数量的1/2到3/4。 减少num_workers进行测试: 步骤: 从较低的num_workers值开始(如1或2),逐步增加并记录每个值下的训练时间。 结果判断:如果在某个特定num_workers值后训练时间突然变长,说明可...
