【问题描述】：

我尝试使用cmake-gui 在ubuntu 上为python2.7 构建opencv3。我的numpy(1.8.2) 由pip 安装（实际上，我也尝试使用apt-get，但错误仍然存在）。每次我使用 cmake-gui 到 Configure 时，都会让我觉得：

Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 63, in apport_excepthook
    from apport.fileutils import likely_packaged, get_recent_crashes
  File "/usr/lib/python3/dist-packages/apport/__init__.py", line 5, in <module>
    from apport.report import Report
  File "/usr/lib/python3/dist-packages/apport/report.py", line 30, in <module>

    from apport.packaging_impl import impl as packaging

    import apt
  File "/usr/lib/python2.7/dist-packages/apt/__init__.py", line 23, in <module>
    import apt_pkg
ImportError: /usr/lib/python2.7/dist-packages/apt_pkg.so: undefined symbol: _Py_ZeroStruct

Original exception was:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/numpy/__init__.py", line 153, in <module>

    from numpy.lib import add_newdoc
  File "/usr/local/lib/python2.7/dist-packages/numpy/lib/__init__.py", line 8, in <module>
    from .type_check import *
  File "/usr/local/lib/python2.7/dist-packages/numpy/lib/type_check.py", line 11, in <module>
    import numpy.core.numeric as _nx
  File "/usr/local/lib/python2.7/dist-packages/numpy/core/__init__.py", line 6, in <module>
    from . import multiarray
ImportError: /usr/local/lib/python2.7/dist-packages/numpy/core/multiarray.so: undefined symbol: _Py_ZeroStruct**strong text**

_Py_ZeroStruct 似乎有问题。我尝试重新安装numpy，但没有成功。

我也试图忽略这个错误并保留make && sudo make install，结果是我可以正确安装我的OpenCV3，但我不能使用python的cv2（没有名为cv2的模块）。因此我相信这个错误是我必须解决的关键问题。

标签： ubuntu numpy cmake opencv3.0

【解决方案1】：

我想通了：

我应该确保dist-package 或site-package 路径都不在$PYTHONPATH 中
