[Question] how to merge two ir_models ?

[Johansmm]

I have tried to blend two models using something like the #63 tool without success (it is not possible to add nodes from one graph to another one).

Is there an optimal way to do something similar to what onnx.compose.merge_models does?

Also, I want to know if there is possible to convert an ir_model into an ir.tape.Tape ? I would like this to make more ease the model merge, removing the dependency to have a graph for each node (initializers are stored into ir.tape._initializers)

1. You can remove the nodes from one graph before adding them to another graph. I will also be working on Graph composition #58 and related tools
2. I think you can initialize a Tape object manually and assign the graph and initializer objects for now.

Thanks @justinchuby for the response. Is it foreseen to create a helper for the second point (convert a graph to Tape)? I think it would be interesting to have it in terms of transferring information between graphs.

Not necessarily a tape but something like that!
