How to train a model in C++ with tensorflow?

Question

I tried to trained a experiment with deep learning model. I found that tensorflow is the best way to do this. But there is problem that tensorflow need to be writen in python. And my program contain many loops.Like this..

for i=1~2000
 for j=1~2000

I know this is a big drawback for python. It's very slow than c. I know tensorfow has a C++ API, but it's not clear. https://www.tensorflow.org/api_docs/cc/index.html (This is the worst Specification I have ever looked) Can someone give me an easy example in that? All I need is two simple code. One is how to create a graph. The other is how to load this graph and run it. I really eager need this.Hope someone can help me out.

It's not so easy, but it is possible. First, you need to create tensorflow graph in python and save it in file. This article may help you

Second, you need to compile libtensorflow, link it to your program (you need tensorflow headers as well, so it's a bit tricky) and load the graph from the file. This article may help you this time
