Ah, it should be pip2 install pyroute2==0.4.10
It did not resolved the issue for me. Even it introduced error *Generic netlink protocol devlink not found*

I have tried all the versions from 0.3 to 0.4.9. Versions from 0.3 to 0.4.9  did not result the below error but still hang issue is there.

root@ubuntu:~# sudo pip2 install pyroute2==0.4.10
