Question

如何在Windows上设置Python（pyflann）上的FLANN？我知道FLANN现在在openCV，但我需要独立版本。 instructions here建议编译FLANN二进制文件或从PointClouds下载版本，但我不能使用其中任何一个版本。

我是从源代码编译的，但是在我尝试运行setup.py之后，我收到了这个错误：

  File "C:\Python27\lib\ntpath.py", line 96, in join assert len(path) > 0
TypeError: object of type 'NoneType' has no len()

有没有人可以帮我解决这个问题，或者让我指向另一个版本的flann，我可以直接安装吗？

Answer 1

将压缩存档解压缩到C:\flann-1.8.4-src\。
以管理员身份打开cmd窗口（右键单击＆gt;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行应安装pyflann，而无需另行拨打setup.py。
