    <div class="sphx-glr-thumbcontainer" tooltip="Larger datasets require more time for training. While by default the models in HiClass are trained using a single core, it is possible to train each local classifier in parallel by leveraging the library Ray [1]_. If Ray is not installed, the parallelism defaults to Joblib. In this example, we demonstrate how to train a hierarchical classifier in parallel by setting the parameter n_jobs to use all the cores available. Training is performed on a mock dataset from Kaggle [2]_.">
