How to use the langdetect.lang_detect_exception.ErrorCode.NeedLoadProfileError function in langdetect

def _create_detector(self):
        if not self.langlist:
            raise LangDetectException(ErrorCode.NeedLoadProfileError, 'Need to load profiles.')
        return Detector(self)

def load_json_profile(self, json_profiles):
        langsize, index = len(json_profiles), 0
        if langsize < 2:
            raise LangDetectException(ErrorCode.NeedLoadProfileError, 'Need more than 2 profiles.')

        for json_profile in json_profiles:
            try:
                json_data = json.loads(json_profile)
                profile = LangProfile(**json_data)
                self.add_profile(profile, index, langsize)
                index += 1
            except:
                raise LangDetectException(ErrorCode.FormatError, 'Profile format error.')
