PaddleDetection 2.0 需要安装paddledet，而paddledet依赖rbox-iou-ops，在安装rbox-iou-ops时报错gcc: error trying to exec 'cc1plus': execvp: No such file or directory。

在stack overflow找到相关的贴子：https://stackoverflow.com/questions/39455741/gcc-error-trying-to-exec-cc1plus-execvp-no-such-file-or-directory，给出了相关解决办法，但没有权限操作。

sudo apt update
sudo apt upgrade
sudo apt install gcc python3-dev python3-pip libxml2-dev libxslt1-dev zlib1g-dev g++

或

sudo apt-get install g++
