我一导入包Python就会中止

我正在WSL（Ubuntu 14.04）上使用Python 3.4.3。以前一切正常。然而，在更新了我所有的pip包和Ubuntu包之后，每当我运行

import theano

时，Python就会中止。如果Python脚本只有那一行，或者我在REPL中运行它，它仍然会中止。如果我导入

pandas

或

keras

，但不导入

numpy

、

scipy

或

nltk

，它也会中止

当我尝试使用GDB调试它时，我得到了以下结果：

Program received signal SIGABRT, Aborted.
0x00007ffffee46c37 in __GI_raise (sig=sig@entry=6)
    at ../nptl/sysdeps/unix/sysv/linux/raise.c:56
56      ../nptl/sysdeps/unix/sysv/linux/raise.c: No such file or directory.

以及stacktrace：

我对GDB和Python不够熟悉，无法进一步调试

我尝试重新安装Python和pip包，但仍然失败。可能有什么问题？

尝试使用虚拟环境。（我知道这不是正确的解决方案）
