初次使用yolov8遇到的问题

news2024/9/29 1:27:15

记录第一次使用yolo8跑自己的数据；

首先将官方文档看一下，大概捉摸了2个小时，地址：GitHub - ultralytics/ultralytics: NEW - YOLOv8 🚀 in PyTorch > ONNX > CoreML > TFLite

获得了基本的一些了解，知道了环境和大概的使用方法；

阅读了官方文档，了解检测任务的训练检测方法，就是各种环境的设置；

官方文档，地址：

CLI - YOLOv8 Docs

然后拿自己处理好的数据进行训练，训练的时候数据格式使用的是yolov5通用的数据格式；

单卡在1070上训练没问题；

然后双卡进行单机多卡训练的时候报错，TypeError: barrier() got an unexpected keyword argument 'device_ids'，报错详情：

Traceback (most recent call last):

网上查了一下，说是pytorch版本不够，然后申请了一个1.9的版本依然出问题：
