按照下面的教程执行RKNN推理测试
https://wiki.luckfox.com/zh/Luckfox-Pico/Luckfox-Pico-RKNN-Test
最后编译出的./rknn_yolov5_demo运行报错:
load lable ./model/coco_80_labels_list.txt
E RKNN: failed to open /dev/rknpu node, need to insmod rknpu dirver!
E RKNN: failed to open device, fd: -2
rknn_init fail! ret=-1
init_yolov5_model fail! ret=-1 model_path=model/yolov5.rknn
这是说系统缺少npu驱动吗?该如何解决?
