跑faster-RCNN代码出现version GLIBCXX_3.4.21 not defined错误怎么办？

Question

问题描述

py3虚拟环境下
gcc version = 4.8.5
跑github上chenyuntc的faster-RCNN代码
https://github.com/chenyuntc/...
到train.py步骤下

出现
ImportError: /home/wendong/anaconda2/envs/wendong/lib/python3.5/site-packages/scipy/spatial/ckdtree.cpython-35m-x86_64-linux-gnu.so: symbol _ZTINSt8ios_base7failureB5cxx11E, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

问题出现的环境背景及自己尝试过哪些方法

尝试修改过libstdc++.so.6的软连接。无论改没改，都显示有GLIBCXX_3.4.21。但是运行train.py还是出这个错无。

你期待的结果是什么？实际看到的错误信息又是什么？

bug体质，已经卡了四天了，跑不通很难受。有没有前辈遇到过这种问题？怎么办？

具体错误信息如下：
