安装paddle之后起不来，报错

Error: Can not import avx core while this file exists: /usr/local/lib64/python3.6/site-packages/paddle/fluid/core_avx.so

问题定位

搜到是/lib64/libstdc++.so.6这个库版本过低，执行命令查看这个动态库支持的CXXABI版本。

[root@bi-server-1 magi_system]# sudo strings /lib64/libstdc++.so.6 | grep 'CXXABI'
CXXABI_1.3
CXXABI_1.3.1
CXXABI_1.3.2
CXXABI_1.3.3
CXXABI_1.3.4
CXXABI_1.3.5
CXXABI_1.3.6
CXXABI_1.3.7
CXXABI_TM_1

解决方案

1） 在本机上试图找到这个库的最新版。

[root@bi-server-1 magi_system]# find / -name 'libstdc++.so*'
/usr/lib/gcc/x86_64-redhat-linux/4.8.2/32/libstdc++.so
/usr/lib/gcc/x86_64-redhat-linux/4.8.2/libstdc++.so
/usr/lib64/libstdc++.so.6
/usr/lib64/libstdc++.so.6.0.19
/usr/share/gdb/auto-load/usr/lib64/libstdc++.so.6.0.19-gdb.py
/usr/share/gdb/auto-load/usr/lib64/libstdc++.so.6.0.19-gdb.pyc
/usr/share/gdb/auto-load/usr/lib64/libstdc++.so.6.0.19-gdb.pyo

这几个库我都用strings看了一下，都没有1.3.8.
2) 从其他地方找
这个网站下载

• 试图 yuminstall失败了。
• wget http://mirror.centos.org/centos/7/os/x86_64/Packages/libstdc+±4.8.5-44.el7.x86_64.rpm
• 发现这个网站对应centos7包版本也是低的。

3. 最终上网直接找到这个so,https://wwa.lanzoui.com/i8lnene。
4. 下下来之后放到/usr/lib64/.
   删除原先的软连接，建立新的软连接

[root@bi-server-1 magi_system]# rm /usr/lib64/libstdc++.so.6
rm: remove symbolic link ‘/usr/lib64/libstdc++.so.6’? y
[root@bi-server-1 magi_system]# ln -s /usr/lib64/libstdc++.so.6.0.26 /usr/lib64/libstdc++.so.6
[root@bi-server-1 magi_system]# sudo strings /lib64/libstdc++.so.6 | grep 'CXXABI'
CXXABI_1.3
CXXABI_1.3.1
CXXABI_1.3.2
CXXABI_1.3.3
CXXABI_1.3.4
CXXABI_1.3.5
CXXABI_1.3.6
CXXABI_1.3.7
CXXABI_1.3.8
CXXABI_1.3.9
CXXABI_1.3.10
CXXABI_1.3.11
CXXABI_1.3.12
CXXABI_TM_1
CXXABI_FLOAT128
CXXABI_1.3
CXXABI_1.3.11
CXXABI_1.3.2
CXXABI_1.3.6
CXXABI_FLOAT128
CXXABI_1.3.12
CXXABI_1.3.9
CXXABI_1.3.1
CXXABI_1.3.5
CXXABI_1.3.8
CXXABI_1.3.4
CXXABI_TM_1
CXXABI_1.3.7
CXXABI_1.3.10
CXXABI_1.3.3

成功
