Training a model
Now that you know how the Jupyter notebook environment works, the real work can begin.
In your notebook environment, open the 1_experiment_train.ipynb
file and follow the instructions directly in the notebook. The instructions guide you through some simple data exploration, experimentation, and model training tasks.

When you save the model, you convert the model to the portable ONNX format. ONNX allows you to transfer models between frameworks with minimal preparation and without the need for rewriting the models.
