Fix NotImplementedError

✅ Solution

The `NotImplementedError` in scikit-learn arises when a method or functionality is declared (e.g., in an abstract base class or for a specific configuration) but lacks a concrete implementation for a specific use case. To fix this, implement the missing functionality by providing the necessary code within the relevant class method, ensuring it handles the specific input and produces the expected output according to the method's defined purpose. If the functionality truly cannot be implemented, consider raising `NotImplementedError` only when the specific problematic conditions are met, and clearly document why it's not supported and suggest alternative approaches or inputs.
