The order betweent import torch and import pandas does matter

hi, I encounter following error if I import torch first and then import pandas:
ImportError GLIBCXX_3.4.21 not found

however, if I import pandas first and then import torch, everything is ok.

can someone give some suggestions for fix the error thoroughly?
my os is CentOS7.4.1708
the version of pytorch is 1.5.0+cpu and anaconda is Anaconda3-2019.03-Linux-x86_64.
