我正在尝试将 GraphLab Create 与 Enthought Canopy iPython 一起使用，但我得到了一个似乎与 unicode 相关的 ImportError。该行是： ImportError: /home/aaron/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/graphlab/cython/cy_ipc.so: undefined symbol: PyUnicodeUCS4_DecodeUTF8

这之前是：

GraphLab 论坛http://forum.graphlab.com/discussion/84/importerror-undefined-symbol-pyunicodeucs4-decodeutf8表明这是由于 Enthought Python 是使用 2 字节宽的 unicode 字符编译的。由于我无法重新编译，有没有办法让 Enthought 使用 4 字节字符？
