conda环境下“/lib64/libstdc++.so.6: version `GLIBCXX_3.4.20‘ not found”问题解决
1 conda环境下运行python程序报错
conda环境下运行python所报的错误信息如下：

从错误中分析可知，报错发生在/lib64/libstdc++.so.6，是GLIBCXX_3.4.20找不到所致。
2.1 命令行查看GLIBCXX的版本信息
命令查看显示如下：
[root@localhost faceswap]# strings /usr/lib64/libstdc++.so.6 |grep GLIBCXX*
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.16
GLIBCXX_3.4.17
GLIBCXX_3.4.18
GLIBCXX_3.4.19
GLIBCXX_DEBUG_MESSAGE_LENGTH本地确实没有GLIBCXX_3.4.20
2.2 查看软连接
[root@localhost faceswap]ls -l /usr/lib64/libstdc++.so*
lrwxrwxrwx. 1 root root 19 5月 6 14:48 /usr/lib64/libstdc++.so.6 -> libstdc++.so.6.0.19

拷贝高版本的libstdc++.so到/usr/lib64目录下，并重新建立软连接
cp /root/anaconda3/envs/faceswap/lib/libstdc++.so.6.0.31 /usr/lib64/
ln -sf /usr/lib64/libstdc++.so.6.0.31 /usr/lib64/libstdc++.so.6
通过命令行查看
(faceswap) [root@localhost faceswap]# strings /usr/lib64/libstdc++.so.6 |grep GLIBCXX*
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2

GLIBCXX_3.4.31问题已经解决！
补充：
如果本地找不到GLIBCXX，升级gcc版本到10后再次查找，升级命令如下
安装centos-release-scl
yum install centos-release-scl -y
安装devtoolset
yum install devtoolset-10-gcc* -y
激活
scl enable devtoolset-10 bash
添加到环境变量
echo "source /opt/rh/devtoolset-10/enable" >> ~/.bash_profile
source /opt/rh/devtoolset-10/enable
查看当前gcc版本
gcc -v
