What if there is a version GLIBCXX_3.4.21 not defined error in running the faster-RCNN code? - Codes Helper

problem description

py3 virtual environment
gcc version = 4.8.5
run the faster-RCNN code of chenyuntc on github
https://github.com/chenyuntc/.
to train.py step

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 libstdcPP.so.6 with link time reference

libstdcPP.so.6GLIBCXX_3.4.21train.py

what result do you expect? What is the error message actually seen?

bug physique, has been stuck for four days, can not run very uncomfortable. Have any seniors ever encountered this kind of problem? What shall I do?

specific error messages are as follows:
