如何指定FastDeploy默认安装的opencv目录

怀疑系统环境没有权限，所以没有加上

应该要怎么弄

python版本吗？ 有安装opencv吗？ pip install opencv-python 注意ubuntu也需要apt-get install libopencv-dev 安装opencv(也可以网上搜下opencv安装)

[monkeycc]

pkg-config --modversion opencv
4.0.1

ubuntu安装后 显示出opencv了

pip uninstall opencv-python
pip install opencv-python

python环境中 也重新安装了

问题依旧 @heliqi

试下找到这个so所在的安装路径，export LD_LIBRARY_PATH看下

[heliqi]

find / -name "libopencv_flann.so" 全局搜下so看看， 如果没有可能ubuntu漏装了opencv的依赖库； 如果存在就 export LD_LIBRARY_PATH=xxx:$LD_LIBRARY_PATH 把找到的路径加入环境变量

尝试安装3.x.x版本的opencv，或者源码编译，试了下opencv-3.4.16版本，解决了。
