2.1 opencv安装
- 可参考网：Home - OpenCV
- ippicv包：https://github.com/opencv/opencv_3rdparty/tree/ippicv/master_20191018/ippicv
- 编译命令：cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D CMAKE_BUILD_TYPE=Release -D BUILD_TIFF=ON
注：在conda环境中，由于安装pytorch，会自动安装“libtiff”，卸载后导致pytorch不能用，然后导致opencv在编译过程中会报错，具体如下：
/usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFReadRGBAStrip@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFReadDirectory@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFWriteEncodedStrip@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFIsTiled@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFWriteScanline@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFGetField@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFScanlineSize@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFWriteDirectory@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFReadEncodedTile@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFReadRGBATile@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFClose@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFClientOpen@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFRGBAImageOK@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFOpen@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFReadEncodedStrip@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFSetField@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFSetWarningHandler@LIBTIFF_4.0' /usr/local/lib/libopencv_imgcodecs.so.4.5.1: undefined reference to `TIFFSetErrorHandler@LIBTIFF_4.0解决方法：
- opencv源码安装编译时候，保证conda环境没有libtiff包名
- 在cmake 编译过程中开启 BUILD_TIFF

2.2 TensorRT安装
- 可参考网：https://developer.nvidia.com/zh-cn/tensorrt，有tar包和deb两种安装方，本文选择tar包进行解压安装。
- 根据tar包解压安装：tar -xvf TensorRT-7.2.3.4.Ubuntu-18.04.x86_64-gnu.cuda-11.1.cudnn8.1.tar.gz
- 安装命令：分别进入python、uff和graphsurgeon根据python环境，进行pip安装相应的包
- vi ~/.bashrc 添加 export LD_LIBRARY_PATH=/usr/local/TensorRT-7.2.3.4/lib:/usr/local/cuda/bin:$LD_LIBRARY_PATH
export INCLUDE_PATH=/usr/local/TensorRT-7.2.3.4/include:/usr/local/cuda/lib64:$INCLUDE_PATH- source ~/.bashrc
