PythonlibOpenNI2.这样的问题

Question

我试图在我的kinect Ubuntu下使用primesense模块。我似乎安装了正确的OpenNI2，因为我能够使用processing的simple库在处理过程中运行示例。我使用pip安装了primesense模块，首先在虚拟环境中安装，然后在系统上安装，得到相同的结果。

在iPython中，我做/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到/usr/lib/libOpenNI2.so创建一个符号，然后改为/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

我是不是做错了什么，或者包坏了吗?在这两种情况下，我能做些什么才能让某些东西正常工作吗？

Answer 1

问题是两件事的结合：

1. 在openni2.initialize()上，我应该传递到Redist目录的路径，它默认为primesense模块中的当前目录。
2. 我没有为我的发行版下载正确的实现(尽管它似乎对处理很好)。我已经下载、构建和安装了OpenNI.master.zip，而我应该下载OpenNI-Linux64-2.2.0.33.tar.zip。
