【使用jupyter快速跑通yolov5】

2023-11-04 14:08:40

不关心yolov5的原理实现，只说怎么跑通代码

第一步 conda install git
第二步 git clone yolov5
运行时问题汇总

第一步 conda install git

就是说没有git，怎么git clone？所以第一步下载git，如果已有可以下一步！
PS：清华源真的下载老是断掉，所以果断换源。
找到conda配置路径直接修改，方便快捷！！！

在C盘找到下面的文件，以记事本方式打开

C:\Users[你的用户名].condarc

删除里面的内容，贴下的源

注：**亲测好用！强烈推荐！！！**2020-05-02 上线，清华大学开源软件镜像站的姐妹站，下载体验极佳，再也不用忍受清华源永远下不完的 pytorch 了。

跟换好源后，在jupyter中新建终端下载
```
conda install git
```

(以下执行命令均在terminal中执行)

第二步 git clone yolov5

这里用的也是github镜像（github.com.cnpmjs.org）

git clone https://github.com.cnpmjs.org/Whiffe/yolov5-deepsort.git

切换到克隆的文件夹下

cd yolov5-deepsort

安装需要的环境

pip install -r requirements.txt

运行代码

python demoX.py

其中yolov5-deepsort中test.mp4即为我们要检测的视频，最后会生成result.mp4作为结果。
如需要更换测试视频，只需要在demoX.py文件中cap = cv2.VideoCapture(’./test.mp4’)修改

运行时问题汇总

RuntimeError: “unfolded2d_copy“ not implemented for ‘Half‘

检测模块中AIDetector_pytorch.py的.half()全部改成.float()

错误:OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized.
允许副本存在，python程序中添加
```
import os
os.environ['KMP_DUPLICATE_LIB_OK'] = 'TRUE'
```
