[FishBotCamera]3.结合YOLO实现检测

@2826778595 既然是数组，遍历读取就好，这个做法没啥问题

[2826778595]

@小鱼 好嘞，谢谢。

新问题：
1、pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple yolov5 我把这行换成yolo8，代码里导入的包也是yolo8，可以运行yolo8的模型吗？
2、同时安装yolo5和8在Linux会产生冲突吗？
担心冲突，所以先问问。

小鱼，我在这一节里启动yolov5的时候提示警告不匹配版本该怎么解决呀，这个不匹配了在rqt里也看不到图像

@2431039560 我也遇到这个问题 请问你是如何解决的呢

[2431039560]

@1004461581 摄像头和小车和电脑在同一个子网下就可以了，改一下IP最后面的那个数字

[1004461581]

@2431039560是udpserver_ip吗，改了这个还是不行哎

[小鱼]

@1004461581 发一下网络结构看看

[1004461581]

@小鱼 感谢已经解决

sudo apt update
sudo apt install python3-pip ros-$ROS_DISTRO-vision-msgs
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple yolov5
为什么运行上面指令之后，我所有曾经成功编译过的代码现在colcon build 之后都会出错了，以前面FishBotCamera为例，我可以成功运行了，但是按照 “3.结合YOLO实现检测”内容操作之后，再运行前面的FishBotCamera，就会出现colcon build 错误，错误指示如下：

@pengzhju 在 [FishBotCamera]3.结合YOLO实现检测 中说：

setuptools

什么系统版本，是不是操作后不小心更新了 setuptools 版本

[pengzhju]

@小鱼 对的小鱼，应该问题出在了setuptools上，这个需要怎么解决呀？

[小鱼]

@pengzhju 搜搜默认版本和怎么回退，我帮你看下我的

fishros$ pip list| grep setuptools
---
setuptools                           59.6.0

[pengzhju]

@小鱼 我的是Ubuntu22.04 humble，是按照图片这个步骤来的，可能我哪里出错了。好的小鱼，我先试一下，谢谢呀

[2290305520]

@1004461581 请问一下是怎么解决的

[2290305520]

@小鱼 请问我运行这段命令后就这样不动了是什么原因？

@2290305520 是不是没有图像数据

[2290305520]

@小鱼 是的，没有图像数据

[小鱼]

@2290305520 没有数据检查下驱动
