1. 概述
Darknet是一個比較小衆的深度學習框架,沒有社區,主要靠作者團隊維護,所以推廣較弱,用的人不多。而且由於維護人員有限,功能也不如 tensorflow 等框架那麼強大,但是該框架還是有一些獨有的優點:
-
易於安裝:在makefile裏面選擇自己需要的附加項(cuda,cudnn,opencv等)直接make即可,幾分鐘完成安裝;
-
沒有任何依賴項:整個框架都用C語言進行編寫,可以不依賴任何庫,連opencv作者都編寫了可以對其進行替代的函數;
-
結構明晰,源代碼查看、修改方便:其框架的基礎文件都在src文件夾,而定義的一些檢測、分類函數則在example文件夾,可根據需要直接對源代碼進行查看和修改;
-
友好python接口:雖然darknet使用c語言進行編寫,但是也提供了python的接口,通過python函數,能夠使用python直接對訓練好的.weight格式的模型進行調用;
-
易於移植:該框架部署到機器本地十分簡單,且可以根據機器情況,使用cpu和gpu,特別是檢測識別任務的本地端部署,darknet會顯得異常方便。
2. 安裝
說明
如果已經配置好 opencv,darknet 的運行結果會直接顯示,若本地沒有 opencv 環境,darknet 運行結果將保存到本地圖片,因此建議先 安裝 opencv。
2.1 CPU 版本安裝
在 Ubuntu 和 Mac 平臺上,命令行依次執行如下命令,完成 darknet
的安裝。
git clone https://github.com/pjreddie/darknet
cd darknet
make
2.2 GPU 版本安裝
-
修改 Makefile 文件,Makefile 文件的前 60 行內容如下,其中需要修改的有第 1、2、3、24、50、52 行,並編譯 darknet
