This error occurs when the attribute "initialized" is not defined for the object "IOLoop". This can happen if you are trying to access an attribute that does not exist or if there is a typo in the attribute name.
To fix this error, check the object's documentation to see if the attribute exists and if it is spelled correctly. If it does not exist, you may need to use a different attribute or method to achieve the desired functionality. If it is spelled incorrectly, correct the spelling and try again.
