Building OpenCV with CUDA gives "Cannot open include file: 'Python.h' "
问题
最近我想要构建支持CUDA的OpenCV，但每次尝试构建时都会遇到这个错误：
F:\OpenCV\openCVGPU\opencv-4.7.0\modules\python\src2\cv2.hpp(20,10): fatal error C1083: Cannot open include file: 'Python.h': No such file or directory (compiling source file F:\OpenCV\openCVGPU\opencv-4.7.0\modules\python\src2\cv2_highgui.cpp) [F:\Build\modules\python3\opencv_python3.vcxproj]

其他信息如下：
-
Python版本为3.9
-
OpenCV从GitHub拉取于2023年2月17日，版本为4.7.0
-
OpenCV Contrib也从GitHub拉取，版本为4.x
-
我还尝试安装了Visual Studio 2022的Build Tools
-
使用Visual Studio 2022和CMake，CMake配置如下：

在经过多次尝试和错误之后，我终于成功构建了它，并解决了import cv2不起作用的问题。
首先，我注意到CMake不知何故分配了错误版本的Python。我使用的是Python 3.9.11。在这里：
Python 3:
Interpreter: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/python.exe (版本 3.10.9)
Libraries: C:/Users/Rufo123/AppData/Local/Programs/Python/Python310/libs/python310.lib (版本 3.10.9)
numpy: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/Lib/site-packages/numpy/core/include (版本)
install path: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/Lib/site-packages/cv2/python-3.10
重置缓存后，现在看起来是这样的：
Python 3:
Interpreter: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/python.exe (版本 3.9.11)
Libraries: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/libs/python39.lib (版本 3.9.11)
numpy: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/lib/site-packages/numpy/core/include (版本 1.24.2)
install path: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/Lib/site-packages/cv2/python-3.9
在这之后，构建成功，没有出现错误。但是还有一个小问题，在尝试import cv2时出现了以下错误：
ImportError: 导入 cv2 时加载 DLL 失败：找不到指定的模块
所以我更新了系统环境变量（PATH和PYTHONPATH），并包括了我能想到的一切：
PATH:
f:\Build\lib\python3\Release\
f:\Build\
f:\Build\install\x64\vc17\bin\
F:\CUDA\bin
F:\CUDA\libnvvp
PYTHONPATH:
f:\Build\python_loader\
f:\Build\bin\Release\
在这之后，错误稍微改变了，并且我注意到现在Python实际上可以看到构建的OpenCV库。
所以我进行了大量的谷歌搜索，这篇帖子帮助了我：importerror-dll-load-failed-while-importing-cv2-the-specified-module-could-not-be-found
然后，我编辑了python_loader/cv2中的config.py文件：
import os
BINARIES_PATHS = [
'F:/Build/bin/Release',
os.path.join('f:\Build\install', 'x64\vc17\bin'),
os.path.join(os.getenv('CUDA_PATH', 'c:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.8'), 'bin')
] + BINARIES_PATHS
所以经过一番努力，我认为**'CUDA_PATH'** 变量在系统环境变量中缺失。
还要感谢@Brian 指引我找到正确的方向。

Hi so after a lot of trial and error, I finally built it successfully and also resolved import cv2 not working.
So First of all I noticed that Cmake somehow assigned wrong version of python
I am using 3.9.11. Here:
Python 3:
Interpreter: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/python.exe (ver 3.10.9)
Libraries: C:/Users/Rufo123/AppData/Local/Programs/Python/Python310/libs/python310.lib (ver 3.10.9)
numpy: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/Lib/site-packages/numpy/core/include (ver )
install path: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/Lib/site-packages/cv2/python-3.10
After reseting cache now it looks like this:
Python 3:
Interpreter: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/python.exe (ver 3.9.11)
Libraries: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/libs/python39.lib (ver 3.9.11)
numpy: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/lib/site-packages/numpy/core/include (ver 1.24.2)
install path: C:/Users/Rufo123/AppData/Local/Programs/Python/Python39/Lib/site-packages/cv2/python-3.9
After this, the build succeded without errors. But there was another catch, after trying to import cv2. This error occured:
ImportError: DLL load failed while importing cv2: The specified module could not be found
So I Updated System Environment Variables (PATH and PYTHONPATH) and included everything that came to my mind:
PATH:
f:\Build\lib\python3\Release\
f:\Build\
f:\Build\install\x64\vc17\bin\
F:\CUDA\bin
F:\CUDA\libnvvp
PYTHONPATH:
f:\Build\python_loader\
f:\Build\bin\Release\
After this the error slightly changed and I noticed that now, the python can actually see the built OpenCV Library.
So I googled a lot and this post helped me: importerror-dll-load-failed-while-importing-cv2-the-specified-module-could-not-be-found
And I edited the config.py in python_loader/cv2
import os
BINARIES_PATHS = [
'F:/Build/bin/Release',
os.path.join('f:\Build\install', 'x64\vc17\bin'),
os.path.join(os.getenv('CUDA_PATH', 'c:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.8'), 'bin')
] + BINARIES_PATHS
So after all I think that 'CUDA_PATH' variable vas missing from System Environment Variables.
Also thanks to @Brian for pointing me in the right direction.
