netron

✓ import netron

Correct import for the library.

Launches a local web server to visualize a model file.

import netron # Start Netron to view a specific model file netron.start('model.onnx')

netron --version

Debug

Known issues

gotchaNetron does not support all model formats; some exotic or custom layers may fail to visualize.

fix

Check the official list of supported formats; convert model to ONNX or supported format.

affects: all

gotchaThe `start()` function blocks execution; it runs a Flask server until manually stopped.

fix

Use `netron.start('model.onnx', host='0.0.0.0', port=8080)` and run in a separate thread if needed.

affects: all
