I am trying to make an SNMP agent following this tutorial: http://www.nealc.com/blog/blog/2013/02/23/writing-an-snmp-agent-with-a-custom-mib-using-pysnmp/
I am using the exact code in the tutorial, but when I run the code it ends in this:

I've been on Google for the last few hours searching but didn't find anything valuable.
Edit: Also when using the code from http://pysnmp.sourceforge.net/examples/current/v3arch/agent/cmdrsp/v2c-custom-scalar-mib-objects.html I get a similar error:
