使用带有enhown的cmake进行python包装

Question

我最近开始尝试从ipython笔记本切换到canopy，这是我从MATLAB切换到的。我正在努力获得类似matlab的开发和研究经验。在

我正在跨平台进行这些设置，但我是从OSX开始的

我一直在尝试安装在canopy中使用的包，其中一些包需要编译，比如SimpleITK和VTK6.0。我把这两个都成功地安装在python2.7的常规安装中，但是在为canopy安装它们时遇到了一些麻烦。现在，我正在用CMAKE重新编译SimpleITK/Superbuild来重新创建python包装器。它要求您的python可执行文件include dir和python lib位置。我发现python可以从系统可执行文件在canopy中，以及带有'mdfind-namepython.h的include dir，这是默认位置，我使用了默认的Python库。在

这些是 在

executeable: /Users/jmerkow/Library/Enthought/Canopy_64bit/User/bin/python

Include: /System/Library/Frameworks/Python.framework/Headers

Lib: /usr/lib/libpython2.7.dylib

但我在make时得到以下错误：

AssertionError: Filename /Applications/Canopy.app/appdata/canopy-1.1.0.1371.macosx-x86_64/Canopy.app/Contents/lib/python2.7/os.py does not start with any of these prefixes: ['/Users/jmerkow/Library/Enthought/Canopy_64bit/User', '/Library/Python/2.7/site-packages', '/Users/jmerkow/Library/Enthought/Canopy_64bit/User/Extras/lib/python', '/Users/jmerkow/Library/Python/2.7/site-packages', '/Users/jmerkow/.local/lib/python/2.7/site-packages', '/Users/jmerkow/Library/Python/2.7/lib/python/site-packages']

另外，任何其他帮助我完成这项工作的建议都是非常受欢迎的

在下面编辑

因此，我尝试使用以下方法进行编译：

/System/Library/Frameworks/Python.framework/Versions/Current/bin/python /System/Library/Frameworks/Python.framework/Versions/Current/include/python2.7/ /System/Library/Frameworks/Python.framework/Versions/Current/lib/libpython2.7.dylib

这个编译和创建的egg文件名为

SimpleITK-0.7.0.dev88_ge297c-py2.7-macosx-10.8-intel.egg

但是我在使用enpkg时得到了以下错误

Traceback (most recent call last): File "/Users/jmerkow/Library/Enthought/Canopy_64bit/User/bin/enpkg", line 10, in sys.exit(main()) File "/Applications/Canopy.app/appdata/canopy-1.1.0.1371.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/enstaller/main.py", line 702, in main reqs.append(Req(name + ' ' + version)) File "/Applications/Canopy.app/appdata/canopy-1.1.0.1371.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/enstaller/resolve.py", line 32, in init raise Exception("Not a valid requirement: %r" % req_string) Exception: Not a valid requirement: 'SimpleITK 0.7.0.dev88_ge297c-py2.7-macosx-10.8-intel.egg'

使用easy_install时，我收到以下错误：

它看起来像是我安装的，所以我尝试导入：

import SimpleITK

Fatal Python error: PyThreadState_Get: no current thread

Abort trap: 6

您已经将SimpleITK配置为使用系统python可执行文件、库和include文件。但是，您正在尝试运行树冠分布。它们不是二进制兼容的，不匹配导致了这种类型的程序终止。在

您的canopy python可执行文件已正确找到： /Users/jmerkow/Library/enhough/cabing_64bit/User/bin/python

但是您需要使PYTHON_INCLUDE_DIR和PYTHON_库保持一致。请尝试以下命令以帮助您确定正确的路径：

查找/Users/jmerkow/Library/enhough/cabing_64bit/-name Python.h 查找/Users/jmerkow/Library/enhough/cabing_64bit/-name lib python*.dylib
