运行rknpu2示例代码报错，镜像是ROC-RK3588S-PC_Ubuntu20.04-Minimal-r21164_v1.0.0c_220621.7z，报错内容如下：
firefly@firefly:~/work/rk/tools/rknpu2/examples/rknn_yolov5_demo/build/build_linux_aarch64$ ./rknn_yolov5_demo ../../model/RK3588/yolov5s-640-640.rknn ../../model/bus.jpg
post process config: box_conf_threshold = 0.50, nms_threshold = 0.60
Read ../../model/bus.jpg ...
img width = 640, img height = 640

然后打印dmesg | grep rknpu，日志如下：
