	<span>Pipeline per l&#39;inferenza
	</span></h1>

<p>La <code>pipeline()</code> rende semplice usare qualsiasi modello dal <a href="https://huggingface.co/models" rel="nofollow">Model Hub</a> per fare inferenza su diversi compiti come generazione del testo, segmentazione di immagini e classificazione di audio. Anche se non hai esperienza con una modalità specifica o non comprendi bene il codice che alimenta i modelli, è comunque possibile utilizzarli con l’opzione <code>pipeline()</code>! Questa esercitazione ti insegnerà a:</p>
<ul><li>Usare una <code>pipeline()</code> per fare inferenza.</li>
<li>Usare uno specifico tokenizer o modello.</li>
<li>Usare una <code>pipeline()</code> per compiti che riguardano audio e video.</li></ul>

	<span>Utilizzo della Pipeline
	</span></h2>

<p>Nonostante ogni compito abbia una <code>pipeline()</code> associata, è più semplice utilizzare l’astrazione generica della <code>pipeline()</code> che contiene tutte quelle specifiche per ogni mansione. La <code>pipeline()</code> carica automaticamente un modello predefinito e un tokenizer in grado di fare inferenza per il tuo compito. </p>

<p>La <code>pipeline()</code> accetta qualsiasi modello dal <a href="https://huggingface.co/models" rel="nofollow">Model Hub</a>. Ci sono tag nel Model Hub che consentono di filtrare i modelli per attività. Una volta che avrai scelto il modello appropriato, caricalo usando la corrispondente classe <code>AutoModelFor</code> e <code>AutoTokenizer</code>. Ad esempio, carica la classe <code>AutoModelForCausalLM</code> per un compito di causal language modeling:</p>

<p>Infine, usare la <code>pipeline()</code> per le attività sulle immagini è praticamente la stessa cosa.</p>
<p>Specifica la tua attività e inserisci l’immagine nel classificatore. L’immagine può essere sia un link che un percorso sul tuo pc in locale. Per esempio, quale specie di gatto è raffigurata qui sotto?</p>
