四、生成 onnx 文件

4.1 下载github代码

git clone https://github.com/RichardoMrMu/deepsort-tensorrt.git
复制代码

4.2 下载预训练模型

ckpt.t7，46MB

下载完成后，将ckpt.t7放到 deep_sort_pytorch/deep_sort/deep/checkpoint/ckpt.t7 路径。

4.3 生成 onnx 文件

# 拷贝文件
cp {deepsort-tensorrt}/exportOnnx.py {deep_sort_pytorch}/

cd deep_sort_pytorch

# 生成onnx文件
python3 exportOnnx.py

# 拷贝onnx文件到对应目录
mv {deep_sort_pytorch}/deepsort.onnx {deepsort-tensorrt}/resources
复制代码

五、生成 deepsort.engine

5.1 拷贝onnx文件到对应目录

mv {deep_sort_pytorch}/deepsort.onnx {deepsort-tensorrt}/resources
复制代码

5.2 生成 CMakeLists.txt 文件

cd {deepsort-tensorrt}

# cmake
mkdir build
cd build

cmake ..
复制代码

5.6 测试引擎是否生成

./demo ../resource/deepsort.engine ../resources/track.txt
复制代码

六、主项目

6.1 下载github代码

# 下载github代码
git clone https://github.com/RichardoMrMu/yolov5-deepsort-tensorrt.git
复制代码

6.2 拷贝engine到对应目录

yolov5-deepsort-tensorrt/engine/yolov5s.engine

yolov5-deepsort-tensorrt/engine/deepsort.engine
复制代码

6.3 修改配置

yolov5-deepsort-tensorrt/src/main.cpp，修改engine的路径。

// before you cmake and make, please change ./src/main.cpp char* yolo_engine = ""; char* sort_engine = ""; to your own path
char* yolo_engine = "yolov5-deepsort-tensorrt/engine/yolov5s.engine";
char* sort_engine = "yolov5-deepsort-tensorrt/engine/deepsort.engine";

// 设置摄像头索引
frame = capture.open(0);

// 显示检测结果
// 在 yolov5-deepsort-tensorrt/src/manager.cpp 文件中，取消注释
showDetection(frame,det);  # 取消注释
复制代码

6.4 生成 CMakeLists.txt 文件

cd yolov5-deepsort-tensorrt

# cmake
mkdir build
cd build

cmake ..
复制代码

6.5 修改 CMakeLists.txt 文件

deepsort-tensorrt/CMakeLists.txt 添加tensorRT库。

# tensorRT
include_directories(/home/yichao/360Downloads/TensorRT-7.1.3.4/include)
link_directories(/home/yichao/360Downloads/TensorRT-7.1.3.4/lib/)
复制代码

deepsort-tensorrt/CMakeLists.txt 添加Eigen库。

七、可能存在的问题

Q1：yaml.load()函数缺少参数错误

运行 python exportOnnx.py 出错。

(venv) yichao@yichao:~/下载/deep_sort_pytorch$ python exportOnnx.py 
Traceback (most recent call last):
  File "exportOnnx.py", line 22, in <module>
    cfg.merge_from_file(args.config_deepsort)
  File "/home/yichao/下载/deep_sort_pytorch/utils/parser.py", line 23, in merge_from_file
    self.update(yaml.load(fo.read()))
TypeError: load() missing 1 required positional argument: 'Loader'
复制代码

错误原因：
yaml.load() 函数的参数不对，缺少 Loader 对象。
yaml.load(CLIN,Loader=yaml.FullLoader) # 加上Loader=yaml.FullLoader 避免警告。

注：yaml版本5.1之后弃用，YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated.

解决办法：
修改 deep_sort_pytorch/utils/parser.py 中的代码。

cfg_dict.update(yaml.load(fo.read()))
改成
cfg_dict.update(yaml.load(fo, Loader=yaml.FullLoader))

复制代码

Q2：缺少 NInfer.h 文件

In file included from /home/yichao/下载/deepsort-tensorrt/include/deepsort.h:6:0,
                 from /home/yichao/下载/deepsort-tensorrt/src/deepsort.cpp:1:

make[1]: *** [CMakeFiles/deepsort.dir/all] Error 2
Makefile:90: recipe for target 'all' failed
make: *** [all] Error 2
复制代码

错误原因：
NvInfer.h 头文件属于 TensorRT 下的一个专有头文件，在编译C++ 代码时需要找到它。

解决办法：
deepsort-tensorrt/CMakeLists.txt，增加tensorRT的依赖库

# tensorRT
include_directories(/home/yichao/360Downloads/TensorRT-7.1.3.4/include)
link_directories(/home/yichao/360Downloads/TensorRT-7.1.3.4/lib/)
复制代码

Q3：缺少 Eigen/Core 文件

/home/yichao/360Downloads/TensorRT-7.1.3.4/include/NvInfer.h:3339:22: note: declared here
 class TRT_DEPRECATED IOutputDimensionsFormula
                      ^~~~~~~~~~~~~~~~~~~~~~~~

复制代码

解决办法：重新make

make -j8
复制代码

/home/yichao/下载/deepsort-tensorrt/include/datatype.h:28:10: fatal error: Eigen/Core: 没有那个文件或目录
 #include <Eigen/Core>
          ^~~~~~~~~~~~

make[1]: *** [CMakeFiles/deepsort.dir/all] Error 2
Makefile:90: recipe for target 'all' failed
make: *** [all] Error 2
复制代码

错误原因：
编译找不到Eigen

解决办法：
1. 安装eigen3，默认安装在 /usr/include/eigen3
sudo apt-get install libeigen3-dev

2. deepsort-tensorrt/CMakeLists.txt，增加eigen3的依赖库
include_directories(/usr/include/eigen3)

# 如果还不成功，尝试创建软链接
sudo ln -s /usr/include/eigen3/Eigen /usr/include/Eigen

3. 重新编译
make clean
make -j8
复制代码

Q4：打不开摄像头

错误原因：
在 yolov5-deepsort-tensorrt/src/main.cpp 文件中，未设置摄像头索引或者设置摄像头失败。
frame = capture.open("");  // 未设置索引
frame = capture.open("0");  // 设置失败，索引为int类型

解决办法：
在 yolov5-deepsort-tensorrt/src/main.cpp 文件中，设置摄像头索引。
frame = capture.open(0);
