ModuleNotFoundError: No module named 'misc'

Open reinforcement_learning/rl_cartpole_batch_coach/rl_cartpole_batch_coach.ipynb and inspect the first cell around sys.path.append("common") and the failing misc import. Reproduce the CI failure by running the notebook or its check; done means the import succeeds and CI completes without this ModuleNotFoundError.
