Urllib3 (1.24.2) or chardet (2.2.1) doesn't match a supported version!

I get this issue for turning on dns multitenant.

bench config dns_multitenant on
/usr/lib/python2.7/site-packages/requests/init.py:91: RequestsDependencyWarning: urllib3 (1.24.2) or chardet (2.2.1) doesn’t match a supported version!

How do I fix it? it seems to happen with a lot of stuff. This was a fresh install centos 7.

If you follow the principles in this link (adjust to your needs), you should be OK
