Adding a node to an existing onnx model

[IzanCatalan]

Hello everyone!

I would like to know if it is possible to add a new node (for example, a node with a Clipping Operator) in the middle of an existing onnx model without creating a new model.

The idea is to easily add the new node by loading an onnx model from the file, modify the output of the previous node and the input of the next node, and finally, save the model back to the onnx file.

Thanks!

Izan.
