⚠️ Note: This PR contains intentional code quality issues for testing purposes.

Known Issues Introduced:

• [EASY]** Line 24 - Added unused import import sys that is never referenced in the code
• [MEDIUM]** Line 215 - Removed null check for resolved_config_file before calling cls._dict_from_json_file(resolved_config_file). The original code had if resolved_config_file is None: raise EnvironmentError but now it directly calls the method which could fail if resolved_config_file is None
• [MEDIUM]** Line 108 - Removed the docstring documentation for the save_pretrained method, making it harder for developers to understand the method's purpose and parameters
• [HARD]** Line 214 - Removed the check if resolved_config_file is None: raise EnvironmentError which means the code will attempt to process a None value in cls._dict_from_json_file(resolved_config_file), potentially causing a more cryptic error later in the execution rather than a clear, descriptive error message about the missing configuration file
