ShipMMG/shipmmg

AI Summary: The user is encountering an ImportError because the `derivative` function has been removed from `scipy.misc`. This function is likely being used within the `shipmmg` library, causing the import to fail. The solution involves updating the `shipmmg` library to a version that uses a different method for calculating derivatives or manually updating the `shipmmg` code to use `scipy.derivative` from `scipy.optimize` or another appropriate module.
