原pytorch模型转换成RKNN模型，转换运行在 Linux PC运行结果：

跑在RK1808运行的结果：这里有1千个float输出。

.........此处省略。

这个是检测算法模型，本来的输出格式如下：
0 0.943490 0.121759 0.082812 0.075000 0.98
0 0.137240 0.093981 0.099479 0.087963 0.86
0 0.166667 0.073148 0.070833 0.068519 0.95
0 0.214323 0.025463 0.055729 0.049074 0.92

问题：
1. 转换后的rknn模型推理结果outputs那么多，和原算法模型的输出不一样。
2. rknn模型的推理结果TOP5是怎么看的，那些值是啥意思。
3.rknn模型的推理结果1千个，怎么分析的呢。

pytorch算法模型转换成rknn的算法模型，其中
rknn.config(mean_values=[[123.675, 116.28, 103.53]], std_values=[[58.395, 58.395, 58.395]], reorder_channel='0 1 2')
mean_values ，std_values 这两个值的设定，对rknn的转换影响大吗？
这两个值具体是根据什么配置的呢？

求解答。
