ploaded the data, we can train the Custom Vision model with <code>train_model</code>. This trains the model on the server and returns a <em>model iteration</em>, which is the result of running the training algorithm on the current set of images. Each time you call <code>train_model</code>, for example to update the model after adding or removing images, you will obtain a different model iteration. In general, you can rely on AzureVision to keep track of the iterations for you, and automatically return the r
