我想查询npu驱动版本，按照瑞芯微教程输入dmesg | grep -i rknpu后报以上信息，请问此输出信息是否正确，另外npu的驱动版本是否应该更新到0.9.2以上版本

您好，该显示时正常的，不影响 rknn 应用，0.8.2版本经过测试可以运行 rknn_model_zoo 中的 rv1106/rv1103 例程。

This issue often disturbs command input. Can it be solved?

To stop the issue from being printed, you can cancel it by closing rkipc with RkLunch-stop.sh. If you want to keep rkipc running, you can edit the /oem/usr/share/rkipc-300w.ini file and set the enable_ive attribute to 0.
