multiarray.so：未定义符号：_Py_ZeroStruct

Question

系统为ubuntu16.04。原始系统python是2.7。运行以下命令时出现错误。运行源代码激活tf进入tf环境，运行python并导入numpy，发生以下错误，需要帮助，如何解决此问题？

(tf) liu@bislab:~$ python
    Python 3.5.2 (default, Nov 23 2017, 16:37:01) 
    [GCC 5.4.0 20160609] on linux
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import numpy
    Traceback (most recent call last):
      File "/usr/local/lib/python2.7/dist-packages/numpy/core/__init__.py", line 16, in <module>
        from . import multiarray
    ImportError: /usr/local/lib/python2.7/dist-packages/numpy/core/multiarray.so: undefined symbol: _Py_ZeroStruct

在处理上述异常期间，发生了另一个异常：

  File "/usr/local/lib/python2.7/dist-packages/numpy/__init__.py", line 142, in <module>

    raise ImportError(msg)
ImportError: 
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.
