The error above is 

ModuleNotFoundError: No module named '_ssl'

So the real problem is my python3 can not import the module _ssl

My python 3.5 was installed from source code. Below are the correct ways to make python 3.5 have _ssl.

1. install openssl-devel by yum(My OS is CentOS)
2. compile your python source code with command (./configure && make && make install)
