RKNN 转化Tensorflow模型python接口正常，C++接口错误

1、步骤：rknn将tensorflow的pb模型转换为*.rknn模型
2、步骤：加载到python接口运行模型可以正常运行：
-->loading model
loading model done
--> Init runtime environment

3.同一个模型加载到C接口报错如下：
This system has 6 processor(s).
Bind NPU process(0) to CPU 4
Bind Display process to CPU 3
Bind VideoCapture process to CPU 2

你可以到置顶帖的QQ群里问下，那边能比较专业回答你的问题。
你这里可以看到的是API版本不一样，可以尝试c版本也用1.2.0的API试试，如果1.2.0能用1.3.0出问题，估计是rknn api的bug。
