简单易上手的在windows部署cmake版paddledetection/yolo(c++)

一.下载源代码

官方地址：
https://gitee.com/paddlepaddle/PaddleDetection

网盘：

二.找到c++部署代码

在这里插入图片描述

我个人为了整体性把src文件里的后缀都改为了cpp

三.改CMakeLists.txt文件

原版cmake文件很繁琐，我改写了一个简洁版的
移植的时候只需要改头文件地址和库文件地址即可

1.改前

四.（windows平台）创造一个文件夹将生成可执行文件需要的库放入

在这里插入图片描述

需要用到gpu，就需要事先配置好cuda这一套的环境变量，就不用在cmakelists里面专门写来引用了，配置方法见http://t.csdn.cn/mgIMD

五.编译的时候遇到的bug

1.xxx已经在obj中定义

在这里插入图片描述
这三个关于main的cpp中只能同事存在一个，看自己需要那个，将不需要的文件里面代码全部注释，，我是使用了main.cpp,反正遇到这种报错通常把一些东西注释掉就能解决

2.error C7555: … requires at least ‘/std:c++latest’ when build in Win10

意思是c++版本低了
在这里插入图片描述
找到cmakelists这句函数，然后我发现我之前写的是17，我改成20之后完美解决。

3.fatal error C1083: 无法打开包括文件: “yaml-cpp/yaml.h”: No such file or directory

其实源cmakelists中是套了一个include(cmake/yaml-cpp.cmake)，来编译


find_package(Git REQUIRED)

include(ExternalProject)

message("${CMAKE_BUILD_TYPE}")

我还是想自己来编译，因为根据之前的经验，这种需要远程下载源码的总是有这样那样的问题。

下载源码

https://github.com/jbeder/yaml-cpp

在这里插入图片描述
我以为只是缺少头文件，cmakelists里面补上之后

出现无法解析的外部符号，大概率是缺少库，然后我去编译yaml-cpp的库。

就是很常规的操作，用cmake … 直接就编译出了一个lib库，很顺利，但是使用的时候显示无法打开此lib
在这里插入图片描述
我再重新生成找原因

注意到这一句Defining YAML_CPP_API for DLL import，然后我搜索这个关键词，搜到了https://blog.csdn.net/m0_37833142/article/details/115180471，
即在cmake后多加了一个参数，就成功可以正常调用了，到底是什么原理，我还得继续学习

cmake -DYAML_BUILD_SHARED_LIBS=ON ..

六.下载模型测试

下载地址：
https://github.com/PaddlePaddle/PaddleDetection/blob/release/2.5/docs/feature_models/PaddleYOLO_MODEL.md
里面有yolo一系列的库
在这里插入图片描述
在部署模型里面选择模型下载，左边导出后的权重那些模型是paddle框架的paddle格式模型，右边onnx指onnx格式模型，_nms表示带NMS后处理，可以直接使用预测出最终检测框结果如python deploy/python/infer.py --model_dir=ppyoloe_crn_l_300e_coco_w_nms/ --image_file=demo/000000014439.jpg --device=GPU；wo_nms表示不带NMS后处理，是测速时使用
在这里插入图片描述

六.改源码

改main.cpp中的这些参数，改成自己装图片和模型的地址
在这里插入图片描述

注意这个参数的值不要改，它的备注显示这个参数已经被废弃，写成true会停止运行
在这里插入图片描述

七.添加dll到exe目录

如果exe文件同一目录没有加需要的动态库，会直接报错，由于找不到 paddle inference.dll，无法继续执行代码。重新安装程序可能会
解决此问题，这种问题很简单解决，直接缺啥补啥就行
请添加图片描述
按照提示补好了的dll库是这样

在这里插入图片描述
然后再次运行

报错应用程序无法正常启动(0xc000007b)。请单击”确定”关闭应用程序，这样就很难弄了，不知道到底缺的是什么，但是可以说出现这种问题还是缺库

在原cmakelists里面找到了玄机。这些都是可执行文件需要的dll
在这里插入图片描述
如果懒得看原代码，有个非常简单的方法

直接在这个项目依赖的第三方库里面找dll文件，全部放到exe同一文件夹就可以

bug记录

由于我下载模型的时候下载错了，只下载了一个pdparams文件，但是很无语的时候并不会有任何报错，只会运行完就停止了，没有报任何异常，看这个object_detector.cpp代码里只有函数实现，没有类实现，真的很奇怪，不知道如何排查哪里出的问题，后来我发现这个类实现在了头文件里，排查到了是我模型的原因。

打注释小窍门

在前面定义这个，然后在需要打印的地方直接输Dlog(你想打印的内容)就可以直接打印。不用每次都cout,endl

#define Dlog(x) std::cout<<x<<std::endl

exe文件运行后无输出直接闪退如何找解决办法
搜索栏搜事件查看器

找到错误处

点开有错误的详细信息，直接用搜索引擎搜索这个异常代码能大致判断是什么问题，给了一个解决思路，不至于不知道到底哪里出了问题
