tensorflow0.80版本编译的时候使用GLIBC_2.15，系统自带的是GLIBC_2.12，所以报错了。
安装新版glibc
1.glibc下载
从http://www.gnu.org/software/libc/ 下载源代码。我下载的版本是2.20，链接地址是http://ftp.gnu.org/gnu/glibc/glibc-2.20.tar.gz

2.安装
因为glibc库使用广泛，为了避免污染当前系统环境，最好自定义安装目录，使用时定义一下环境变量就行了。具体步骤如下：

我使用的法（直接升级glibc）：

wget http://ftp.gnu.org/pub/gnu/glibc/glibc-2.17.tar.xz
xz -d glibc-2.17.tar.xz
tar -xvf glibc-2.17.tar
cd glibc-2.17
mkdir build
cd build
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make && make install
需要等大概10分钟。
输入strings /lib64/libc.so.6|grep GLIBC发现已经更新

没有GLIBCXX_3.4.14版本支持，继续安装(注意：libstdc++6_4.7.2-5_amd64.deb这是64位，libstdc++6_4.7.2-5_i386.deb这个是32位)

从网上下载libstdc++.so.6.0.20

http://ftp.de.debian.org/debian/pool/main/g/gcc-4.8/
或者
http://download.csdn.net/detail/pomelover/7524227

放到/usr/lib64/下
#chmod +x libstdc++.so.6.0.20
#rm libstdc++.so.6
#ln -s libstdc++.so.6.0.20 libstdc++.so.6
#strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX

ImportError: cannot import name pywrap_tensorflow

edit: The real fix for me was to updated setuptools to the latest and it allowed me to upgrade mock and six to the latest. I was on setuptools 3.3. In my case I also had to remove said modules by hand because they were owned by OS in '/usr/local/lib/python2.7/dist-packages/'
check versions of everything

pip freeze | grep -e six -e mock
easy_install --version
Update everything

wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
pip install mock --upgrade
pip install six --upgrade

终于成功了。
>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> sess.run(hello)
Hello, TensorFlow!
>>> a = tf.constant(10)
>>> b = tf.constant(32)
>>> sess.run(a+b)
42
>>>

>>> print product
Tensor("MatMul:0", shape=(1, 1), dtype=float32)
>>> sess = tf.Session()
>>> result = sess.run(product)
>>> print result
[[ 12.]]
>>> sess.close()
>>> exit()
