ModuleNotFoundError: No module named 'misc'

Open reinforcement_learning/rl_resource_allocation_ray_customEnv/rl_vehicle_routing_problem_ray_custom.ipynb and inspect the first cell, especially its sys.path setup and the common import. Run the notebook's CI validation to reproduce the ModuleNotFoundError; done means the notebook completes that import and passes CI.
