搭建YOLOv10环境 训练+推理+模型评估

---

前言

本文将详细介绍跑通YOLOv10的流程，并给各位提供用于训练、评估和模型推理的脚本

---

一、环境搭建

必要环境

本文使用Windows10+Python3.8+CUDA10.2+CUDNN8.0.4作为基础环境，使用30系或40系显卡的小伙伴请安装11.0以上版本的CUDA

1. 创建yolov10虚拟环境

conda create -n yolov10 python=3.8

2. 下载pytorch (pytorch版本>=1.8)

pip install torch==1.9.1+cu102 torchvision==0.10.1+cu102 torchaudio==0.9.1 -f https://download.pytorch.org/whl/torch_stable.html

若使用的是AMD显卡或不使用GPU的同学 可以通过以下命令可以安装CPU版本

pip install torch==1.9.1+cpu torchvision==0.10.1+cpu torchaudio==0.9.1 -f https://download.pytorch.org/whl/torch_stable.html

3. 下载YOLOv10源码

地址：https://github.com/THU-MIG/yolov10

4. 安装所需要的依赖包

pip install -r requirements.txt

二、推理测试

1. 将如下代码复制到ultralytics文件夹同级目录下并运行 即可得到推理结果

2. 关键参数

1. 测试图片：–source 变量后填写图像文件夹路径 如：default=r"images"
2. 测试视频：–source 变量后填写视频路径 如：default=r"video.mp4"

三、训练及评估

1. 数据结构介绍

这里使用的数据集是VOC2007，用留出法将数据按9:1的比例划分成了训练集和验证集

2. 配置文件修改

3. 训练/评估模型

将如下代码复制到ultralytics文件夹同级目录下并运行 即可开始训练

# -*- coding:utf-8 -*-
from ultralytics import YOLOv10
import argparse# 解析命令行参数
parser = argparse.ArgumentParser(description='Train or validate YOLO model.')
# train用于训练原始模型  val 用于得到精度指标
parser.add_argument('--mode', type=str, default='train', help='Mode of operation.')
# 预训练模型
parser.add_argument('--weights', type=str, default='yolov10n.pt', help='Path to model file.')
# 数据集存放路径
parser.add_argument('--data', type=str, default='VOC2007/data.yaml', help='Path to data file.')
parser.add_argument('--epoch', type=int, default=200, help='Number of epochs.')
parser.add_argument('--batch', type=int, default=8, help='Batch size.')
parser.add_argument('--workers', type=int, default=0, help='Number of workers.')
parser.add_argument('--device', type=str, default='0', help='Device to use.')
parser.add_argument('--name', type=str, default='', help='Name data file.')
args = parser.parse_args()def train(model, data, epoch, batch, workers, device, name):model.train(data=data, epochs=epoch, batch=batch, workers=workers, device=device, name=name)def validate(model, data, batch, workers, device, name):model.val(data=data, batch=batch, workers=workers, device=device, name=name)def main():model = YOLOv10(args.weights)if args.mode == 'train':train(model, args.data, args.epoch, args.batch, args.workers, args.device, args.name)else:validate(model, args.data, args.batch, args.workers, args.device, args.name)if __name__ == '__main__':main()

4. 关键参数

1. 模式选择：
–mode train: 开始训练模型
–mode val: 进行模型验证

2. 训练轮数： 通过 --epoch 参数设置训练轮数,默认为200轮。该参数控制模型在训练集上迭代的次数,增加轮数有助于提升模型性能,但同时也会增加训练时间。

3. 训练批次： 通过 --batch 参数设置训练批次大小,一般设置为2的倍数,如8或16。批次大小决定了每次参数更新时使用的样本数量,较大的批次有助于加速收敛,但会增加显存占用，需根据实际显存大小进行调整

4. 训练数据加载进程数： 通过 --workers 参数设置数据加载进程数,默认为8。该参数控制了在训练期间用于加载和预处理数据的进程数量。增加进程数可以加快数据的加载速度，linux系统下一般设置为8或16，windows系统设置为0。

训练过程：
训练结束后模型已经训练过程默认会保存到runs/detect/exp路径下

5. 单独对训练好的模型将进行评估

1. 将 --mode变量后改为val 如：default=“val”
2. 将 --weights变量后改为要单独评估的模型路径 如：default=r"runs/detect/exp/weights/best.pt"

评估过程：
