Hi @Teju-chitara, thanks for the details.

Could you verify the version of PyYAML installed on your system?

pip show pyyaml

Below is the output i am getting

[ec2-user@ip-172-31-30-164 ~]$ pip3 show pyyaml Name: PyYAML Version: 3.12 Summary: YAML parser and emitter for Python Home-page: http://pyyaml.org/wiki/PyYAML Author: Kirill Simonov Author-email: xi@resolvent.net License: MIT Location: /usr/lib64/python3.6/site-packages Requires: [ec2-user@ip-172-31-30-164 ~]$

Ok, that's interesting. Lmctl requires PyYAML>=5.3.0,<6.0 so I think if you upgrade PyYAML to a 5.x version it might resolve this?

pip install pyyaml -U

or

pip install pyyaml==5.4.1
