请教一下初始化错误会是什么原因？

日志如下：

WAKEUP CALLBACK: encount error - Error Domain=38 Code=2490374 "Wakeup: engine initialize failed." UserInfo={NSLocalizedDescription=Wakeup: engine initialize failed., NSHelpAnchor=}.

代码如下：        

        self.wakeupEventManager?.setDelegate(self);

        self.wakeupEventManager?.setParameter("****", forKey: BDS_WAKEUP_APP_CODE);

        let mod = Bundle.main.path(forResource: "bds_easr_basic_model", ofType: "dat");

        let words = Bundle.main.path(forResource: "cmd", ofType: "bin");

        self.wakeupEventManager?.setParameter(words, forKey: BDS_WAKEUP_WORDS_FILE_PATH);

        self.wakeupEventManager?.setParameter(mod, forKey: BDS_WAKEUP_DAT_FILE_PATH);

        self.wakeupEventManager?.setParameter(nil, forKey:BDS_WAKEUP_AUDIO_FILE_PATH);

        self.wakeupEventManager?.setParameter(nil, forKey:BDS_WAKEUP_AUDIO_INPUT_STREAM);

        self.wakeupEventManager?.sendCommand(BDS_WP_CMD_LOAD_ENGINE);

        self.wakeupEventManager?.sendCommand(BDS_WP_CMD_START);
