python：未定义符号：PyUnicodeUCS2_DecodeUTF8

Question

当我尝试在 python 中执行我的主文件时遇到问题（我在 Ubuntu 12.04 和 python 2.7 上）。 我收到此错误：

michael@michael-laptop-ubuntu:~/rubyWorkSpace/pymcs$ python __main__.py Traceback (most recent call last):
  File "__main__.py", line 9, in <module>
    sys.exit(main())
  File "__main__.py", line 5, in main
    import launch
  File "/home/michael/rubyWorkSpace/pymcs/launch.py", line 2, in <module>
    import src.lib.utils as fn
  File "/home/michael/rubyWorkSpace/pymcs/src/lib/utils.py", line 4, in <module>
    import scipy.signal, numdisplay, sys

    import orthogonal
  File "/home/michael/.local/lib/python2.7/site-packages/scipy/special/orthogonal.py", line 697, in <module>
    from orthogonal_eval import \
ImportError: /home/michael/.local/lib/python2.7/site-packages/scipy/special/orthogonal_eval.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8

目前 scipy 安装了Python Package Manager （请参阅我以前的帖子：python : scipy install on ubuntu。

谢谢。

您运行代码时使用的 Python 解释器与用于编译 scipy 的解释器不同。这通常发生在使用 Unicode UCS2 支持编译的 Python 安装运行针对具有 Unicode UCS4 支持的 Python 安装编译的模块时（反之亦然）。您需要使用用于运行代码的 Python 解释器重新编译/重新安装 scipy 安装。
