TB-RV1126Ds按照rknn教程操作，推理报错

刷完最新固件后，系统正常启动，按照TB-RV1126Ds开发板rknn教程安装时均正常，但运行Python DEMO进行推理时报错如下：
在调用rknpu中的api进行初始化时，一样会有如下提示：

1. librknn_runtime version 1.7.0 (0bef7b3 build: 2021-08-18 19:55:01 base: 1131)
   
2. [     1] Failed to open device: No such file or directory, Try again...

6. [     5] _OpenDevice(1091): FATAL: Failed to open device, errno=No such file or directory.

复制代码我尝试过更新rknpu驱动，重新刷固件等都无法解决。

所以你是在1126板子上跑一个target=1109的模型?

这是DEMO里面直接运行的结果，我自己用C++接口出现一样的错误，不管换什么模型都一样，跟target没有关系

我看了里面的源码，如下所示，这个DEMO是按照教程中执行的，位置在/vendor/etc/model/test.py中，所用模型为rv1109_rv1126目录中，并没有单独的rv1126文件夹，我自己生成的模型，target为rv1126，一样出现这样的错误

有人遇到同样问题，链接但是我并没有找到update.img在哪

需要安装rknn-rv1126 ，重启后驱动才会加载。

我的安装后，重启了还是这样，是不是有其他问题？

目前安装、重启、运行demo的输出如下，能否帮忙分析下是哪里问题？

复制代码在安装过程中出现了“Setting locale failed.”和“No such file or directory”不知道有没有影响

你试下使用root来执行
