At https://neuralmmo.github.io/build/html/rst/baselines.html the suggest that you could change "scale".
But trying the suggested commandline:
python main.py train --config=baselines.Medium --scale=Baseline --RESTORE=None
You are just getting the error:
AssertionError: CLI argument: scale is not a Config property
My guess is that it happens because the order of the commands.
If you take a look at https://github.com/NeuralMMO/baselines/blob/main/main.py#L188
Those lines should probably be placed before:
config = attrgetter(config)(base_config)()
config.override(**kwargs)
Or else the "scale"-Parameter will be passed directly to the config-class ...
