简介

推荐 GitHub 上一款开箱即用的 C++ AI 模型工具箱：Lite.AI.ToolKit，涵盖目标检测、人脸检测、人脸识别、语义分割、抠图等领域。

 

里面包括了 70+ 流行开源模型，如最新的 RVM、YOLOX、YoloV5、DeepLabV3、ArcFace 等模型，对用户友好，简单易用。

GitHub：github.com/DefTruth/lite.ai.toolkit

环境

WSL2 Ubuntu18.04

配置

配置预编译库：

1. 下载预编译好的库

2 . 配置

通过命令 vim ~/.bashrc 打开.bashrc，然后添加

export LD_LIBRARY_PATH=YOUR-PATH-TO/lite.ai.toolkit/lib:$LD_LIBRARY_PATH
export LIBRARY_PATH=YOUR-PATH-TO/lite.ai.toolkit/lib:$LIBRARY_PATH

执行 source ~/.bashrc

注意事项：

lite.ai.toolkit/lib 里面库之间的软连接失效，需要重新创建软连接，否则编译时会报错；

主要修改一下浅蓝色的库：

编译

查看build.sh

#!/bin/bash
 
BUILD_DIR=build
 
if [ ! -d "${BUILD_DIR}" ]; then
  mkdir "${BUILD_DIR}"
  echo "creating build dir: ${BUILD_DIR} ..."
else
  echo "build dir: ${BUILD_DIR} directory exist! ..."
fi
 
cd "${BUILD_DIR}" && pwd && cmake .. \
  -DCMAKE_BUILD_TYPE=MinSizeRel \
  -DINCLUDE_OPENCV=ON \
  -DENABLE_MNN=ON \
  -DENABLE_NCNN=OFF \
  -DENABLE_TNN=OFF &&
  make -j8

设置了-DENABLE_MNN=ON，因为需要配置MNN库和头文件，将MNN-2.0.0/build/install 下面的库和头文件，放置到上面步骤的lite.ai.toolkit文件夹下面的库、头文件目录下即可；

执行编译：

cd lite.ai.toolkit-main
./build.sh

编译完成后，可执行程序在 lite.ai.toolkit-main/build/lite.ai.toolkit/bin；

头文件：lite.ai.toolkit-main/build/lite.ai.toolkit/include

库：lite.ai.toolkit-main/build/lite.ai.toolkit/lib
