我已经使用Tensorflow进行了几个月的编程，但现在当我尝试导入它的包时，我得到了一个Segmentation错误，如下所示：
> ipython3
Python 3.5.2 (default, Nov 17 2016, 17:05:23)
Type 'copyright', 'credits' or 'license' for more information
IPython 6.0.0 -- An enhanced Interactive Python. Type '?' for help.
In [1]: import tensorflow
Segmentation fault (core dumped)
>
我在运行gdb时重现了这个问题。为此，我编写了一个只有这一行的程序main.py：
import tensorflow
然后我在gdb下运行python3 main.py;底部错误：
> gdb --args python3 main.py

strlen () at ../sysdeps/x86_64/strlen.S:106
106 ../sysdeps/x86_64/strlen.S: No such file or directory.
(gdb)
知道问题可能是什么，或者我可以收集哪些其他信息来排除故障？我的猜测是我最近安装的，但无法想到具体的东西。这里有一些相关的环境变量：
CUDA_HOME=/usr/local/cuda
LD_LIBRARY_PATH=/usr/local/lib/cuda/lib64:/usr/local/cuda-8.0/lib64
请注意，在导入Tensorflow软件包时，即使在尝试打开CUDA库之前，问题就会立即发生，这与this other issue不同。
我正在运行Python 3.5.2，所有已安装的软件包都更新到最新版本，包括在Ubuntu 16.04下的tensorflow-gpu（1.1.0）。
谢谢！
更新：这是gdb bt
