[经验分享] LicheePi 4A问题记录与解决手动挂载npu驱动

wuboy 2023-11-10 14:47 楼主

环境：debian系统 镜像20231023
报错信息如下：

```

(ort) root@lpi4a:/home/sipeed/Desktop/udisk/yolov5n_jiancai# python3 inference.py
 ********** preprocess image **********
 ******* run yolov5 and postprocess *******
FATAL: could not open driver '/dev/vha0': No such file or directory
Please create or load network object first.
Could not retrieve inputs of network object
Could not retrieve inputs of network object
Could not retrieve outputs of network object
Segmentation fault
```
解决办法（如果lsmod检测驱动没挂载可以只执行后面几步，镜像默认会驱动挂载，然后我也不知道为什么会没挂载，然后可以手动挂载）：

```
