计算棒运行官网的mobilenet_v1示例报错

arm环境，看报错是识别到计算棒序列号了的，但是又报RKNN_ERR_DEVICE_UNAVAILABLE，各位有遇到这个情况吗？

重新刷了flashtool_1.5.2.tgz后，
[toybrick@rk1808 ~]$ rpm -qa | grep rknn
rknn-api-1.4.1-0.rk1808.fc28.aarch64
rknn-server-1.4.1-0.rk1808.fc28.aarch64
rknn-1.4.1-0.rk1808.fc28.aarch64
计算棒降到1.4.1的api也不行。官网这个demo现在还能跑不 ？

已解决，没升级本地rknn。
