python - 安装 dlib python 模块出现段错误

Question

我正在尝试安装 dlib python 模块，但每次尝试导入它时，都会出现段错误并且 python 崩溃，如下所示。

└[~/Devspace/dlib]> python 
Python 2.7.10 (default, Sep 23 2015, 04:34:21) 
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.72)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import dlib
[1]    50326 segmentation fault  python

我没有收到任何其他错误消息，因此我不确定如何解决此问题。我在 OS X 上使用 homebrew 安装了 boost 和 python(并通过系统 python 进行了符号链接(symbolic link))。我一直在四处搜索，发现这通常是由 boost 和 python 版本不兼容引起的，这可能是由于使用自制版本的库引起的与系统Python。我相当确定这就是原因，但 CMake 在编译时告诉我这一点

-- Detecting CXX compile features - done
-- Boost version: 1.59.0
-- Found the following Boost libraries:
--   python
-- Found PythonLibs: /usr/local/Cellar/python/2.7.10_2/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib (found suitable version "2.7.10", minimum required is "2.6")
-- USING BOOST_LIBS: /usr/local/lib/libboost_python-mt.dylib
-- USING PYTHON_LIBS: /usr/local/Cellar/python/2.7.10_2/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib
-- Enabling SSE4 instructions
 *****************************************************************************

所以我知道 python 库和 boost 库都来自自制程序管理的 /usr/local/bin 而不是系统管理的 /usr/bin/ 。使完成良好并返回成功，甚至似乎安装一切都很好。

之后它就安装在我的python站点包中并且可以用pip看到

└[~/Devspace/dlib]> pip freeze      
appnope==0.1.0
colorama==0.3.3
cv2==1.0
cycler==0.9.0
decorator==4.0.4
dlib==18.18.99
gnureadline==6.3.3
imutils==0.3

但如果我尝试导入它，它总是会导致段错误。我正在使用包含的 setup.py 进行安装，并且认为如果 python/boost 不匹配，我可能需要自己运行 CMake，但它们对我来说看起来很好。有人对我有什么建议吗？任何帮助将不胜感激。
