数据准备相应的问题V2

想请教下数据导入的问题：
这个参考链接已看：
https://github.com/alibaba/euler/wiki/%E6%95%B0%E6%8D%AE%E5%87%86%E5%A4%87
是用户只需要生产simple_meta.json -i simple_graph.json 这两个文件，生成simple_graph.dat，直接读取simple_graph.dat就可以了是么？

因为看到ppi目录下还有别的json文件，以及参考了https://www.cnblogs.com/shiyublog/p/9819086.html这篇文章，看了下源码，貌似是tf_euler/python/euler_ops/base.py中读取_LIB.CreateGraph(config)来构建图，
不知道是否要产生别的json文件，谢谢谢谢～

Start with the linked data-preparation wiki page and inspect tf_euler/python/euler_ops/base.py at the _LIB.CreateGraph(config) call. Compare the documented simple_meta.json and simple_graph.json flow with the additional JSON files in the ppi directory. Done means the documentation clearly states which inputs are required, how simple_graph.dat is produced, and how it is read.
