Introduction
To edit an ONNX model, One common way is to visualize the model graph, and edit it using ONNX Python API. This works fine. However, we have to code to edit, then visualize to check. The two processes may iterate for many times, which is time-consuming.
What if we have a tool, which allow us edit and preview the editing effect in a totally visualization fashion? Then onnx-modifier comes. With it, we can focus on editing the model graph in the visualization pannel. Finally, all editing information will be summarized and processed by Python ONNX automatically. Most importantly, our time will be saved!
onnx-modifier is built based on the popular network viewer netron and the lightweight web application framework flask.
Currently, the following editing operations are supported:
- Delete a single node.
- Delete a node and all the nodes rooted with it.
- Recover/Reset a node.
Hope it helps!
Get started
Install the require Python packages by
pip install onnx
pip install flask
Then run
python app.py
Click the url in the output info generated by flask (http://127.0.0.1:5000/ for example), then onnx-modifier will be launched in the web browser.
Click Open Model... to upload the onnx model to edit. The model will be parsed and show on the page.
