OpenCV 安装错误：没有这样的文件或目录"pyopencv_generated_include.h"

Question

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

知道什么嘶吼吗？

我有CUDA 9.2，Python 3.6.5。查看此处给出的安装说明：https://www.pyimagesearch.com/2018/05/28/ubuntu-18-04-how-to-install-opencv/

我在OpenCV安装过程中遇到了同样的问题。

我们需要手动执行生成脚本(从/build 一级，在我的情况下，从/opencv-3.4.3，为你，基于你的 opencv 版本是/opencv-3.4.1(。

因此，如果您在/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

很抱歉回复晚了，但对于遇到此问题的其他任何人，请尝试检查您将 OpenCV 克隆到的目录名称。

我用一些奇怪的名字把它改成"opencv"，然后更新了cmakelist.txt它构建得很好
