如何在 Windows 上的 Python (pyflann) 上设置 FLANN？我知道 FLANN 现在在 openCV 中，但我需要独立版本。这里的说明建议编译 FLANN 二进制文件或从PointClouds下载一个版本，但我不能使用其中任何一个。

我从源代码编译但在尝试运行后setup.py出现此错误：

>

Traceback (most recent call last):

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

谁能帮我解决这个问题或将我引导到我可以简单安装的另一个版本的 flann 吗？

  • 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 > 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

该nmake install线路应该pyflann安装而无需setup.py单独调用。
