I have cloned DRL-OR and configured the environment according to Readme on Ubuntu 20.04. But when I run run.sh in drl-or, I got error:

ConnectionRefusedError:[Error 111] Connection refused

so I guess whether it's Mininet, ryu or the system version.

By the way, I run the code in VMware workstation Pro 16

It works fine on my server with Ubuntu 20.04, Mininet 2.3.0.dev6 and Ryu 4.34. Both Mininet and Ryu are of the latest version on PyPI. But I guess the reason why your problem occurred is that drl-or/run.sh was launched before testbed/run.sh. I think the correct order of launching is ryu-controller/run.sh, testbed/run.sh and drl-or/run.sh, because DRL-OR has to establish connection with Mininet (the testbed) before the algorithm starts working.
