     model. This can be done using the open-source tool [netron](https://github.com/lutzroeder/netron). You can either
     try it out directly in [webbrowser](https://netron.app/) or you can install it locally using `pip install netron`
     and then run it using `netron resnet18.onnx`. Can you figure out what method of the model is exported to ONNX?
