前言

寒假训练了4个版本的yolo，其中yolov4和yolov4-tiny是基于darknet的。由于都是在colab上训练的，不好展示，所以打算在win10上跑一下，因此本文旨在win10编译darknet的踩坑记录。

安装Visual Studio

这个不用多说，安装2017或者2019版就行，需要开启英语语言

安装CUDA

参考上一篇安装CUDA就行，需要CUDAv10.0以上，并且安装时要点VS集成

vcpkg安装

参考vcpkg的官方下载方式，powershell中执行如下命令

1
2
3
git clone https://github.com/microsoft/vcpkg
cd vcpkg
bootstrap-vcpkg.bat

如果执行bootstrap-vcpkg.bat时，下载vcpkg.exe遇到网络问题，可以直接去release里面下载二进制文件

vcpkg安装依赖

根据AlexeyAB的repo说明，powershell执行如下命令

1
vcpkg install darknet[full]:x64-windows

遇到的问题

事后得知，此处遇到的网络问题可以试一试校园网，校园网似乎对从外网下载文件有较好的效果

安装opencv时，需要从raw.githubusercontent.com下载东西，然而遇到了host问题。首先尝试修改了host，结果遇到了SSL connect error问题，于是在加了几个host发现还是失败了。遂尝试使用VPN代理，按照输出将HTTP_PROXY和HTTPS_PROXY加入到环境变量，依然不行。尝试直接在powershell中使用变量。

1
2
$env:HTTPS_PROXY="https://127.0.0.1:7890/"
$env:HTTP_PROXY="http://127.0.0.1:7890/"

此时的staus输出为

Failed. Status: 4;"A requested feature, protocol or option was not found built-in in this libcurl due to a build-time decision."

Failed to download file.
If you use a proxy, please set the HTTPS_PROXY and HTTP_PROXY environment variables to "https://user:password@your-proxy-ip-address:port/".

If error with status 4 (Issue #15434),
try setting "http://user:password@your-proxy-ip-address:port/".

Otherwise, please submit an issue at https://github.com/Microsoft/vcpkg/issues

因此根据要求执行下面代码

1
$env:HTTPS_PROXY="http://127.0.0.1:7890/"

此时重新执行安装命令，即可完成下载。

  scripts/ports.cmake:133 (include)

尝试如下指令

1
vcpkg install darknet[opencv-base,cuda,cudnn]:x64-windows

编译darknet

提前安装ninja并添加到环境变量

修改Makefile

GPU=1
CUDNN=1
CUDNN_HALF=1
OPENCV=1

#我是gtx1050，根据makefile里面的注释自己的修改
ARCH= -gencode arch=compute_61,code=sm_61 -gencode arch=compute_61,code=compute_61

按照AlexeyAB的repo，执行如下代码，注意CMake的版本，过低将无法编译。注意下面的顺序，如果有问题需要清理一下缓存，不然会一直编译失败

4
$env:VCPKG_ROOT="vcpkg的位置"
git clone https://github.com/AlexeyAB/darknet
cd darknet
powershell -ExecutionPolicy Bypass -File .\build.ps1

如果正确执行上述步骤的话，编译是不会出错的

测试darknet
