rk1808S0无法在rk3566上init初始化

环境如下：主控端：rknn_toolkit_lite: 1.7.5  设备端： rknn_toolkit_lite: 1.7.5程序代码：
def load_model(modle_path):
        # Create RKNN object
        rknn = RKNN()

        print("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")
        print('-->loading model')
        rknn.load_rknn(modle_path)
        print('loading model done')

        # init runtime environment
        print('--> Init runtime environment')
        ret = rknn.init_runtime(target="rk1808")
        if ret != 0:
                print('Init runtime environment failed')
                exit(ret)
        print('done')
        print("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")
        return rknn

报错信息如下-->loading model
loading model done

执行./npu_transfer_proxy devices是可以识别到设备
