Thanks for the advice about the converter . It works very well for me . I converted the h5 model and got myself those Json files too .
But now I have have no clue how to implement it , like how to call and use the method on the web … what will be the function name . It would be awesome if you can give me further knowledge or examples on this objective .
I have google myself for the answer , and I find most of the examples revolves around using python to print the web .
This sounds very strange to me , I only have the experience on NodeJS (haven’t touch it for a year already though ) and on hands AJAX  for web , building web with python is frontier for me , at best I wish I can use the tools I already learnt , it would be grateful if there are examples on implementing model into AJAX that I haven’t know yet  .
Looking forwards for your reply , many thanks .
