| 🤗 <em>Datasets</em> est une bibliothèque open-source permettant de télécharger et de préparer des jeux de données à partir de toutes les modalités, y compris l’audio. | |
| La bibliothèque offre un accès facile à une sélection inégalée de jeux de données d’apprentissage automatique accessibles sur Hugging Face Hub. | |
| De plus, 🤗 <em>Datasets</em> comprend de multiples fonctionnalités adaptées aux jeux de données audio simplifiant le travail avec de tels jeux de données pour les chercheurs et les praticiens. | |
| Pour commencer à utiliser des jeux de données audio, assurez-vous que la 🤗 <em>Datasets</em> est installée :</p> <div class="code-block relative"><div class="absolute top-2.5 right-4"><button class="inline-flex items-center relative text-sm focus:text-green-500 cursor-pointer focus:outline-none transition duration-200 ease-in-out opacity-0 mx-0.5 text-gray-600 " title="code excerpt" type="button"><svg class="" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" fill="currentColor" focusable="false" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 32 32"><path d="M28,10V28H10V10H28m0-2H10a2,2,0,0,0-2,2V28a2,2,0,0,0,2,2H28a2,2,0,0,0,2-2V10a2,2,0,0,0-2-2Z" transform="translate(0)"></path><path d="M4,18H2V4A2,2,0,0,1,4,2H18V4H4Z" transform="translate(0)"></path><rect fill="none" width="32" height="32"></rect></svg> <div class="absolute pointer-events-none transition-opacity bg-black text-white py-1 px-2 leading-tight rounded font-normal shadow left-1/2 top-full transform -translate-x-1/2 translate-y-2 opacity-0"><div class="absolute bottom-full left-1/2 transform -translate-x-1/2 w-0 h-0 border-black border-4 border-t-0" style="border-left-color: transparent; border-right-color: transparent; "></div> Copied</div></button></div> <pre class=""><!-- HTML_TAG_START -->pip install datasets[audio]<!-- HTML_TAG_END --></pre></div> <p data-svelte-h="svelte-19ww6hu">L’une des principales caractéristiques déterminantes de 🤗 <em>Datasets</em> est la possibilité de télécharger et de préparer un jeu de données en une seule ligne de code Python à l’aide de la fonction <code>load_dataset()</code>. | |
