1. Precautions

1. After a lot of testing and switching between many driver and cuda versions, found that CUDA10.2+YOLOv3 are the fastest. Other versions are inefficient and have a serious performance loss.

   NVIDIA	GeForce RTX 2080 Ti GeForce RTX 2060
   Driver	456.71	!important
   Driver Date	2020/9/30
   Driver Version	27.21.14.5671
   CUDA	10.2	cuda_10.2.89_441.22_win10.exe
   NVCC	10.2	!important
   cuDNN	10.2	!important
   YOLO	V3 (code for 2019)	!important

2. Make sure that the graphics driver is not automatically updated to the latest version.
   This guarantees the best performance of YOLOv3.

3. If you get the "yolo_cpp.dll.dll not found" error, you need to recompile the yolo_v3.dll with VS2019, not the VS2022.

4. Watch this: Install & test YoloV3 on Windows 10

2. Usage

1, Download all the files

2, Unzip the files by WinRAR via "Extract Here",

    1. /Darknet.YoloV3/cudnn64_7.zip
    2. /voc_custom/backup/yolov3_custom_63000.zip

3. Change the path in `GlobalSatics.cs`
4. Start and enjoy it

PS:

1. I changed the `Alturos.Yolo.dll` and `yolo_cpp_dll_gpu.dll` to fix the issus, 
    so DO **NOT** use the default DLLs by nuget(You can use the nuget install the Alturos.YOLO package，
    and replace the dlls with mine).
2. The `packages` files is modified by me.
3. The `example` images are for testing.
4. The `voc_custom` files are my custom training model.

3. Issues Fixed

Error 1. System.DllNotFoundException - `Microsoft Visual C++ 2015-2019 Redistributable (x64)

```
in `.\src\Alturos.Yolo\DefaultYoloSystemValidator.cs`, line: 51
add more vc++ versions check, and recompile

var checkKeys = new Dictionary ...
{
    ...
    { @"Installer\Dependencies\VC,redist.x64,amd64,14.27,bundle", "Microsoft Visual C++ 2015-2019 Redistributable (x64)" },
    { @"Installer\Dependencies\VC,redist.x64,amd64,14.28,bundle", "Microsoft Visual C++ 2015-2019 Redistributable (x64)" },
    { @"Installer\Dependencies\VC,redist.x64,amd64,14.29,bundle", "Microsoft Visual C++ 2015-2019 Redistributable (x64)" }
};
```

Error 2. System.DllNotFoundException - Unable to load DLL 'yolo_cpp_dll_gpu.dll': The specified module could not be found.

prepare the Yolo_cpp_dll.dll(GPU mode), you can follow the tutorial in my channel here
https://youtu.be/zT8eDXpslXw

1. complied the dll Yolo_cpp_dll.dll
2. prepare to replace it to the original yolo_cpp_dll_gpu.dll, KEEP with the original name yolo_cpp_dll_gpu.dll

Error 3. YOLO.Detect(File.ReadAllBytes(imagPath)); //System.NotImplementedException: 'C++ dll compiled incorrectly'
