python - OpenCV安装报错: No such file or directory "pyopencv_generated_include.h"

Question

尝试在 linux 18.0.4 中安装 OpenCV 时，在执行 sudo make install 命令后出现以下错误，停止了执行。

[ 83%] Linking CXX executable ../../bin/opencv_perf_stitching

知道发生了什么吗？

我有 CUDA 9.2、Python 3.6.5。按照此处给出的安装说明进行操作。:https://www.pyimagesearch.com/2018/05/28/ubuntu-18-04-how-to-install-opencv/

我在安装 OpenCV 时遇到了同样的问题。

我们需要手动执行 gen 脚本(从/build 向上一级，在我的例子中，从/opencv-3.4.3，对你来说，基于你的 opencv 版本是/opencv-3.4.1)。

所以，如果你在/build 中:

cd ..
python ./modules/python/src2/gen2.py ./build/modules/python_bindings_generator ./build/modules/python_bindings_generator/headers.txt
cd build
sudo make install
