With the latest odltools, the following exception is seen while executing the command ‘python -m odltools netvirt show neutron all’

The RestClient is not getting initialized from method ‘get_models(self, args, models)’ in mdsal/models/models.py

All netvirt command options are getting failed for the same reason.
