	<span>Quickstart

<p>🤗 Optimum Habana was designed with one goal in mind: <strong>making training and evaluation straightforward for any 🤗 Transformers user while leveraging the complete power of Gaudi processors</strong>.
There are two main classes one needs to know:</p>
<ul><li><a href="/docs/optimum.habana/pr_356/en/trainer#optimum.habana.GaudiTrainer">GaudiTrainer</a>: the trainer class that takes care of compiling (lazy or eager mode) and distributing the model to run on HPUs, and of performing traning and evaluation.</li>
<li><a href="/docs/optimum.habana/pr_356/en/gaudi_config#optimum.habana.GaudiConfig">GaudiConfig</a>: the class that enables to configure Habana Mixed Precision and to decide whether optimized operators and optimizers should be used or not.</li></ul>
<p>The <code>GaudiTrainer</code> is very similar to the <a href="https://huggingface.co/docs/transformers/main_classes/trainer" rel="nofollow">🤗 Transformers Trainer</a>, and adapting a script using the Trainer to make it work with Gaudi will mostly consist in simply swapping the <code>Trainer</code> class for the <code>GaudiTrainer</code> one.
That is how most of the <a href="https://github.com/huggingface/optimum-habana/tree/main/examples" rel="nofollow">example scripts</a> were adapted from their <a href="https://github.com/huggingface/transformers/tree/main/examples/pytorch" rel="nofollow">original counterparts</a>.</p>
