在使用小鱼的yolov5_ros2功能包时，编译环节出现问题

[LeeSonFirm]

ubuntu20.04，ros foxy中，前面按照步骤，到编译的时候出现问题，运行指令colcon build后，桌面上会出现一个绿色框框显示成功，但是终端里头就输出了一行字：summary：0 packages finished[0.51S]
求各位大佬帮忙!

[小伊]

当colcon build命令执行后只输出了“summary: 0 packages finished [0.51s]”这样的信息时，这通常意味着colcon没有找到任何要构建的工作空间包（workspace packages）。这可能是因为以下几个原因：

1. 工作空间未正确设置：确保你已经在包含yolov5_ros2功能包的ROS 2工作空间目录中执行了colcon build命令。
2. CMakeLists.txt或package.xml缺失或不正确：检查yolov5_ros2功能包中是否包含了必要的CMakeLists.txt和package.xml文件，并且这些文件的内容是正确的。
3. colcon未找到包：可能是因为COLCON_IGNORE文件或.colconignore文件阻止了colcon扫描到该包，或者包的路径没有正确设置。
4. 依赖项问题：如果yolov5_ros2依赖于其他尚未安装或构建的包，colcon也可能不会尝试构建它。

以下是一些解决步骤：

1. 确认工作空间：

   • 切换到你的ROS 2工作空间目录，通常是一个包含src子目录的目录。
   • 确保yolov5_ros2功能包位于src子目录中。

2. 检查CMakeLists.txt和package.xml：

   • 导航到yolov5_ros2功能包的目录中。
   • 检查是否存在CMakeLists.txt和package.xml文件，并且它们的内容是正确的。

3. 检查COLCON_IGNORE或.colconignore：

   • 在你的工作空间目录中查找名为COLCON_IGNORE或.colconignore的文件。
   • 确保这些文件没有错误地阻止了colcon扫描到yolov5_ros2功能包。

4. 检查依赖项：

   • 阅读yolov5_ros2的文档或package.xml文件，了解它的依赖项。
   • 确保所有必需的依赖项都已安装。

5. 重新配置工作空间：

   • 在工作空间目录中运行colcon build --symlink-install来重新配置和构建工作空间。
   • 注意--symlink-install选项，它允许使用符号链接来避免不必要的文件复制，这可以加快构建过程。

6. 查看详细输出：

   • 你可以通过添加--verbose或-v选项来运行colcon build命令，以获取更详细的输出信息。
   • 这可能会帮助你诊断问题所在。

7. 清理工作空间：

   • 如果之前的工作空间构建失败了，并且现在出现了这个问题，尝试清理工作空间并重新构建。
   • 在工作空间目录中运行colcon build --packages-select yolov5_ros2 --cmake-args -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CXX_FLAGS="-Wall -Wextra"来单独构建yolov5_ros2包，并添加一些调试标志。

如果以上步骤都不能解决问题，请考虑查看yolov5_ros2功能包的文档或寻求其维护者的帮助。

每看出和yolo相关的日志，请提供完整的上下文和操作流程和日志

[LeeSonFirm]

@小鱼
请问下好的安装包在哪个目录里面啊，好像关于yolo的包没下载下来

[LeeSonFirm]

@小鱼
找不到yolov5的包

[小鱼]

@LeeSonFirm 下载到哪个目录是你自己决定的

[LeeSonFirm]

@小鱼
当时没设置位置，直接粘贴代码了，现在不知道在哪，还有办法找出来吗

这样算是下好了吗，下好了的话在哪个目录里面呢

[LeeSonFirm]

@小鱼
DeprecationWarning: pkg_resources is deprecated as an API.是这个原因没下载下来吗

[小鱼]

@LeeSonFirm 这个是下好了，下好了的目录有提示

@LeeSonFirm 在 在使用小鱼的yolov5_ros2功能包时，编译环节出现问题 中说：

Requirement already satisfied: yolov5 in ./.local/lib/python3.8/site-packages (7.0.13)

不过这只是依赖，并不是功能包

[LeeSonFirm]

@小鱼
是的，我找不到yolov5的功能包，请问后续需要怎样操作呢？

[小鱼]

@LeeSonFirm 根据教程下载功能包就可以了

[LeeSonFirm]

@小鱼
我按照教程用那个pip3 install指令没有下载下来，输入代码之后显示的就是我上面发的

[LeeSonFirm]

@小鱼 是需要我去下载您在GitHub上给的yolov5_ros2的源码吗，然后放到这个依赖所在的目录中进行编译？

[小鱼]

@LeeSonFirm 你看教程，按着教程走就可以了

[LeeSonFirm]

@小鱼 我已经严格按照教程执行，可是输入pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple yolov5之后，我找不到这个功能包，并且无法进行编译
