使用pip安装tensorflow 0.80，python 使用tensorflow 0.80遇到的问题及处理方法

http://blog.csdn.net/levy_cui/article/details/51251095

1.python 版本切换到2.7

推荐使用pythonbrew，http://blog.csdn.net/nuccch/article/details/17595161

2.pip安装相关包

安装tensorflow
pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl

ImportError: /lib64/libc.so.6: version `GLIBC_2.15' not found (required by /usr/local/python27/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so)


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。

我使用的方法（直接升级glibc）：

yum install gcc

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)

下载新版本，地址：http://ftp.de.debian.org/debian/pool/main/g/gcc-4.7/libstdc++6_4.7.2-5_amd64.deb
ar -x libstdc++6_4.7.2-5_amd64.deb&&tar xvf data.tar.gz

从网上下载libstdc++.so.6.0.20 

推荐下载：

http://download.csdn.net/download/arackethis/8395651

（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
