Utility scripts for editing or modifying onnx models. The script edits and modifies an onnx model to extract a subgraph based on input/output node names and shapes.

usage: onnx_edit.py [-h] [--inputs INPUTS] [--outputs OUTPUTS] [--skipverify] input output

positional arguments:

input input onnx model
output output onnx model

optional arguments:

-h, --help show this help message and exit

--inputs INPUTS comma separated model input names appended with shapes, e.g. --inputs nodename1[1,2,3],nodename2[1,2,3]

--outputs OUTPUTS comma separated model output names appended with shapes, e.g. --outputs outnodename1[1,2,3],outnodename2[1,2,3]

--skipverify skip verification of model. Useful if shapes are not known

usage: onnx_summarize.py [-h] input

Creates a summary of operators in the input onnx file and also dumps each loop body as an onnx file and also creates summary for each such loop body.
