Error: NameError: name 'Vector' is not defined

When I use run_eval.py, parameters like this parser.add_argument('--mode', '-m', type=str, default='eval', choices=['train_agent', 'train_scenario', 'eval']) parser.add_argument('--agent_cfg', nargs='', type=str, default=['adv_scenic.yaml']) parser.add_argument('--scenario_cfg', nargs='', type=str, default=['eval_scenic.yaml'])

but got something error:

adv_scenic.yaml eval_scenic.yaml failed!

I've encountered the same situation. The problem was solved after I upgraded my Python version from 3.8.0 to 3.8.16.

Hi, yeah, exactly, it is due to the python version, you should use 3.8.16, i will also add the version requirement to repo later.
