onnxifier 2.0.3

An Open Neural Network Exchange (ONNX) Optimization and Transformation Tool.

ONNXifier

A simple tool to convert any IR format to ONNX file.

Framework	Status
OpenVINO	✅
ONNXRuntime	✅

• ✅: well supported
• 🪛: partially supported
• 🚧: developing

Usage

1. Install from PyPI

pip install onnxifier

2. Convert IR using CLI

onnxify model.xml

usage: onnxify input_model.xml [output_model.onnx]

onnxify command-line api

options:
  -h, --help            show this help message and exit
  -a [ACTIVATE ...], --activate [ACTIVATE ...]
                        select passes to be activated, activate L1, L2 and L3 passes if not set.
  -r [REMOVE ...], --remove [REMOVE ...]
                        specify passes to be removed from activated passes.
  -n, --no-passes       do not run any optimizing passes, just convert the model
  --print [PRINT]       print the name of all optimizing passes
  --format {protobuf,textproto,json,onnxtxt}
                        onnx file format
  -s, --infer-shapes    infer model shapes
  -c CONFIG_FILE, --config-file CONFIG_FILE
                        specify a json-format config file for passes
  -u, --uncheck         no checking output model
  --check               check optimized model with random inputs
  --checker-backend {onnx,openvino,onnxruntime}
                        backend for accuracy checking, defaults to openvino
  -v OPSET_VERSION, --opset-version OPSET_VERSION
                        target opset version, defaults to 19
  -vv [{DEBUG,INFO,WARNING,ERROR,CRITICAL}], --log-level [{DEBUG,INFO,WARNING,ERROR,CRITICAL}]
                        specify the level of log messages to be printed, defaults to INFO
  -R, --recursive       recursively optimize nested functions
  --nodes [NODES ...]   specify a set of node names to apply passes only on these nodes

To print pass information:

onnxify --print all
onnxify --print fuse_swish
onnxify --print l1

TODO

• [OV] Add Loop support.
• [OV] Add NMS support.
• [OV] Add If support.
• [ONNX] Support to optimize If.
