tensorrtx/retinaface/calibrator.cpp:4:31: 致命错误:opencv2/dnn/dnn.hpp:没有那个文件或目录
如果没有文件 /usr/local/include/opencv4/opencv2/dnn/dnn.hpp
则需要安装opencv-4.1.0
(一)安装依赖
sudo yum install gcc gcc-c++
sudo yum install cmake3
sudo yum install gtk2-devel
sudo yum install gtk3-devel
sudo yum install ant
(二)下载源码opencv-4.1.0.zip
https://github.com/opencv/opencv/archive/4.1.0.zip
cd /usr/local/
unzip opencv-4.1.0.zip
cd /usr/local/opencv-4.1.0/
mkdir build
cd build
编译&安装
