Python breaks as soon as I import the package

I am using Python 3.4.3 on WSL (Ubuntu 14.04). Everything was fine before. However, after updating all packages and packages Ubuntu Python is aborted when I run import theano

. If the Python script only has one line, or I run it in the REPL, it still breaks. It also breaks if I import pandas

either keras

, but not numpy

, scipy

or nltk

.

When I tried to use GDB to debug it, I got this:

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.

      

        
        
        
      

    

And the stacktrace:

I'm not familiar enough with GDB and Python to debug further.

I tried reinstalling Python and pip packages, but it still breaks. What could be wrong?
