rknn 板端运行程序Invalid RKNN model version 6， Meet unsupported rknn target type

E RKNN: [09:15:53.053] 6, 1
E RKNN: [09:15:53.053] Invalid RKNN model version 6
E RKNN: [09:15:53.053] rknn_init, load model failed!
[NN_ERROR] rknn_init fail! ret=-1
 

或者报错：

E RKNN: [08:35:30.804] Meet unsupported target type: 0x46495247
E RKNN: [08:35:30.804] Meet unsupported target type: 0x46495247

以及：E RKNN: [09:30:22.952] Meet unsupported rknn target type: 0x46495247

在板端运行报错，解决：librknnrt.so 库不匹配

把编译环境中用到的librknnrt.so 库，复制到板端的/usr/lib库就行.

编译环境的librknnrt和板端的librknnrt版本不一致导致。
