Hello Everyone, I am stuck . please help
I was following the Making a New Learning Environment
on https://github.com/Unity-Technologi...eate-New.md#making-a-new-learning-environment

and at the point where i have to start training, when i type the command
mlagents-learn config/rollerball_config.yaml --run-id=RollerBall
in anaconda prompt

I receive the following error

Same here. Did you solve it?

 

Find the config YAML file in the ml-agents directory and remove any hyperparameter named beta_schedule.
