ModuleNotFoundError: No module named 'misc'

Open reinforcement_learning/rl_portfolio_management_coach_customEnv/rl_portfolio_management_coach_customEnv.ipynb and run its first cell in the CI environment. Check how the notebook adds the common path and resolves misc.get_execution_role and wait_for_s3_object; done means the notebook passes CI without the ModuleNotFoundError.
