Question

我正在尝试在Ubuntu下使用我的kinect上的Python primesense模块。我似乎正确安装了OpenNI2，因为我能够使用处理的simple-openni库运行处理精细的示例。我使用pip安装了primesense模块，先在virtualenv中安装，然后在系统上安装相同的结果。

从iPython，我接收以下内容：

In [1]: from primesense import openni2

In [2]: openni2.initialize()
---------------------------------------------------------------------------
InitializationError                       Traceback (most recent call last)
<ipython-input-2-4a1f095d5922> in <module>()
----> 1 openni2.initialize()

/usr/local/lib/python2.7/dist-packages/primesense/openni2.pyc in initialize(dll_directories)
     95     if not found:
     96         raise InitializationError("OpenNI2 could not be loaded:\n    %s" %
---> 97             ("\n    ".join("%s: %s" % (dir, ex) for dir, ex in exceptions)),)
     98 
     99     _openni2_initialized = True

InitializationError: OpenNI2 could not be loaded:
    /home/escher/pyenv/libOpenNI2.so: file does not exist

我尝试从/usr/lib/libOpenNI.so创建符号到/usr/lib/libOpenNI2.so，然后我更改为/ usr / lib /目录。这就是我得到的：

openni2.initialize()
---------------------------------------------------------------------------
InitializationError                       Traceback (most recent call last)
<ipython-input-5-4a1f095d5922> in <module>()
----> 1 openni2.initialize()

/usr/local/lib/python2.7/dist-packages/primesense/openni2.pyc in initialize(dll_directories)
     95     if not found:
     96         raise InitializationError("OpenNI2 could not be loaded:\n    %s" %
---> 97             ("\n    ".join("%s: %s" % (dir, ex) for dir, ex in exceptions)),)
     98 
     99     _openni2_initialized = True

InitializationError: OpenNI2 could not be loaded:
    /usr/lib/libOpenNI2.so: /usr/lib/libOpenNI2.so: undefined symbol: oniInitialize

我做错了什么，或者包装是否破损，无论哪种情况，我能做些什么才能让工作变得有效？

问题是两件事的结合：

在openni2.initialize（）上，我应该将路径传递给Redist目录，它默认为primesense模块中的当前目录。
我没有为我的发行版下载正确的实现（虽然它似乎可以正常处理）。我已经下载，构建并安装了OpenNI.master.zip，我应该下载OpenNI-Linux-x64-2.2.0.33.tar.zip。
