环境

Ubuntu:22.10
Docker:24.0.0

下载源码

这里我下载了6.0版本的，想要别的版本的自己修改，但dockerfile可能目录不同，可以通过find指令查询

git clone -b v6.0 https://github.com/ultralytics/yolov5.git

构建Docker镜像

这里要等待很长时间，构建大概20g的镜像

sudo docker build -f [your dockerfile path] -t [your image name]:[version] .

运行docker镜像

# 创建后台运行的docker 容器
sudo docker run -itd -w /workspace -v [your youlov5 path]:/workspace --net=host --ipc=host --gpus=all -e DISPLAY=$DISPLAY --env="QT_X11_NO_MITSHM=1" --name [your container name] [your image name]:[version] /bin/bash

# 进入docker容器
sudo docker exec -it [your container name] /bin/bash

运行目标检测

python detect.py --source [your picture path] --view-img

出现partially initialized module ‘cv2’ has no attribute '_registerMatType’错误

具体错误详情：

Traceback (most recent call last):
  File "detect.py", line 14, in <module>
    import cv2
  File "/opt/conda/lib/python3.8/site-packages/cv2/__init__.py", line 181, in <module>

    cv._registerMatType(Mat)
AttributeError: partially initialized module 'cv2' has no attribute '_registerMatType' (most likely due to a circular import)

这是因为版本不匹配的问题，Dockerfile中只限制了opencv-python的版本大于4.1.2并没有限制最高版本，最高版本是，这里我们重新安装

sudo pip install 'opencv-python>=4.1.2,<4.3' --force-reinstall

重新运行

python detect.py --source [your picture path] --view-img

出现ImportError: libSM.so.6: cannot open shared object file: No such file or directory错误

具体错误详情：

Traceback (most recent call last):
  File "detect.py", line 14, in <module>
    import cv2
  File "/opt/conda/lib/python3.8/site-packages/cv2/__init__.py", line 5, in <module>
    from .cv2 import *
ImportError: libSM.so.6: cannot open shared object file: No such file or directory

这是没有库文件的原因，执行以下命令：

sudo apt-get install libsm6 libxrender1

重新运行

python detect.py --source [your picture path] --view-img

出现AttributeError: ‘Upsample’ object has no attribute 'recompute_scale_factor’错误

    raise AttributeError("'{}' object has no attribute '{}'".format(

需要根据出错目录去修改upsampling.py文件，具体修改方法参考recompute_scale_factor错误参考
修改完毕后重新运行：

python detect.py --source [your picture path] --view-img

出现如下提示就是成功，如果出现x server的问题请看参考链接：
