我在官方下载的2系列软件文档，比如<寒武纪 CNRT 用户手册>，里面很多接口我这边都是不存在的，比如cnrtRet_t cnrtDeviceGetAttribute(int *pValue, cnrtDeviceAttr_t attr, int device);和cnrtRet_t cnrtGetDevice(int *pOrdinal);，当然远远不止这两个接口不能用。

用户手册版本：寒武纪运⾏时库⽤⼾⼿册    版本 6.0.0

平台：arm64
代码：已经包含了#include <bang.h>，#include <cnrt.h>和#include <cn_api.h>

而且，文档中出现了许多不知含义的变量类型，如cnrtDeviceAttr_t ，可能这个在源文件中有详细说明，但是我这个sdk中也没有。

其他问题：cngdb在b站视频给的开源地址不能用了，麻烦工程师给个能用的地址；
