I'm not familiar with the CentOS7 packaging, but as a sanity check I ran `pip install greenlet==0.4.9 eventlet==0.18.4` in a python2 virtualenv then in a python2 interpreter `from eventlet import greenpool` runs successfully. I would try running this import by hand on your system to see if you can get any more information. Could be a packaging issue or potentially some sort of name collision between script names?<br>
