如何在Windows上的Python（pyflann）上设置FLANN？我知道弗兰恩现在在openCV中，但我需要独立的版本。instructions here建议编译FLANN二进制文件或从PointClouds下载一个版本，但我不能使用这些。
我从源代码编译，但在尝试运行setup.py之后，出现以下错误：
>
C:\Python27\flann-1.8.4-src\src\python>python setup.py install
running install

Traceback (most recent call last):

有谁能帮我解决这个问题，或指导我到另一个版本的弗兰恩，我可以简单地安装？
最佳答案
将压缩的存档文件解压缩到C:\flann-1.8.4-src\。
以管理员身份打开cmd窗口（右键单击>以管理员身份运行）
然后执行以下操作：
cd C:\flann-1.8.4-src\
mkdir build
cd build
cmake .. -G "NMake Makefiles"
nmake install
nmake install行应该安装pyflann而不需要单独调用setup.py。关于python - 如何在Windows上安装FLANN和pyflann，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/18163132/
